How to choose the right fiber laser cutting source

As laser technology develops, high power fiber laser cutting source is certainly one tend in future. What’s more, those high power fiber laser source has appeared.  First let me show you the most popular high power fiber laser source in China market.

  

In China laser market, of course raycus brand fiber laser source occupied the very big market share.

Since 2007, Raycus has continuously accumulated technical strength in the field of fiber lasers. It has been working in the fields of 1.5KW, 2KW, 3KW and 4KW or higher for many years.

Before the mass launch into the market, it has done nearly 2 years on actual cutting verification in key customer plants. It is only for fully confirmed.

The laser will be put into the market in batches when it is stable for a long time!

introduction

After all, high power fiber lasers account for the highest cost in the entire device. So many end customers will be the first to understand the differences in configuration, performance, reliability, and after-sales between different lasers. We have done some in-depth information. Hope to let everyone know the system fiber laser and to help the terminal customers choose the right type.

The excellent characteristics of fiber lasers make more and more end customers pay attention to and consider replacing the original processing methods with fiber laser solutions in metal processing. With the localization of high-power fiber lasers, the cost of various core devices has greatly reduced, so the selection threshold of high-power lasers has begun to disappear.

 More information of high power fiber laser source will come soon..

Principle and function of fiber laser marking laser

Principle and function of fiber laser marking laser. Then, in the industrial manufacturing industry, the application of fiber laser marking machine is indispensable.  And its core component fiber laser plays a huge role.

Then, a fiber laser is a laser that uses a rare earth-doped glass fiber as a gain medium and can develop on the basis of a fiber amplifier.

Under the action of pump light, it is easy to form high power density in the fiber, which causes the laser energy level of the laser working substance to “reverse the number of particles”.

Then, and a positive feedback loop (constituting a resonant cavity) can appropriately form to form a laser oscillation output.

Then, fiber laser applications are widely used, including laser fiber communication, laser space long-distance communication, industrial shipbuilding, laser engraving, laser marking, laser cutting, printing rolls, metal non-metallic drilling / cutting / welding / (brazing, Quenching, cladding and deep welding).

Military defense and security, medical equipment and equipment, large-scale infrastructure.

Fiber laser advantages:

1. Then, glass fiber has low manufacturing cost, mature technology, and the advantages of miniaturization and intensification brought about by the flexibility of its fiber.

2. The glass fiber does not require strict phase matching of the incident pump light as the crystal, which is due to the non-uniform broadening caused by the splitting of the glass matrix Stark, resulting in a wide absorption band.

3. Then, the fiber material has a very low volume to area ratio, fast heat dissipation, low loss, and low laser threshold.

4. The output laser has many wavelengths, which is because the rare earth ions have very rich energy levels and many kinds of rare earth ions.

5. Good tunability, thanks to the wide range of rare earth ion energy levels and the broad spectrum of glass fibers.

6. Since there is no optical lens in the cavity of the fiber laser, it has the advantages of no adjustment, no maintenance. And high stability, which is unmatched by conventional lasers.

7. Then, the fiber is exported, making the laser easy to handle a variety of multi-dimensional arbitrary space processing applications. Making the design of the mechanical system very simple.

8. Can handle the harsh working environment and have high tolerance to dust, vibration, shock, humidity and temperature.

9. No need for electric cooling and water cooling, only air cooling is required.

10. Then, has high electro-optic efficiency. Its integrated electro-optical efficiency is as high as 20% or more. Which can greatly save power consumption during operation and save operating costs.

Different Fiber Laser Source Brand-Wendy from XT Laser

Different Fiber Laser Source Brand

When it comes to fiber laser. We can think about Raycus,IPG,MAX,N-Light.But what is difference between them?

Raycus&Max

China famous brand: Raycus and Max Photonics . Raycus is a little expensive than Max Photonics.  while more stable than Max Photonics.

Usually Max to dometic customers. Max Failure rate is higher than Raycus.  i don’t recommend it to you.  may be its price is not high, but it will cost more maintenance fee.

IPG&Raycus

IPG is Germany brand.  very famous fiber laser source in market.  and it’s orginal imported. Raycus brand made in China, quality also stability. We think Raycus is more cost-effective than IPG brand. But some customers very like and trust „made in Germany“, so IPG is optional.

Generally speaking, most of customers prefer to Raycus brand, some customers from European and USA prefer to IPG brand, some customers with tight budget like to choose Max Photonics.

We suggest you to choose Raycus brand first, IPG as optional.

Raycus, IPG&N-Light

Than this „N-LIGHT laser source“ . differs from the usual laser emitter?N-LIGHT , Raycus, IPG are three popular band laser source in market,Raycus and IPG are for normal metal.  such as carbon steel, stainless steel , galvanized sheet .etc.  not high reflective metal.But some clients want to cut some high reflective metals, such as aluminium, copper, brass, etc.
If use Raycus or IPG to cut high reflective metal, laser source will alarm, and do harm to laser source, because laser beam will return back to laser generator.
But N-LIGHT laser source, it has Back-reflection isolation, so it can not only cut carbon steel, stainless steel , galvanized sheet .etc, not high reflective metal, and  high reflective metals, such as aluminium, copper, brass, etc.

Fiber laser source plays a major role in a fiber laser marking machine.

Performance of fiber laser source

1. High power

A multimode pump diode module group can radiate 100 watts optical power. And we can also design a laser source with very high power output.

2. No thermoelectric cooler required

This high-power, wide-faced multimode diode can operate at very high temperatures with minimal air cooling and low cost.

3. Wide pump wavelength

High-power fiber laser has a wide and flat light-wave absorption region(930-970nm). Therefore, pump diodes do not require any type of wavelength stabilization device.

4. Efficient

The pump light passes through the core of the single-mode fiber many times. So it has high utilization.

5. High reliability

Multimode pump diodes are much more stable than single mode pump diodes. Its geometric wide surface makes the optical power density on the cross section of the laser very low. The current density through the active surface is low as well. In this way, the pump diode has a reliable operating life of more than 100,000 hours.

Different brands of fiber laser source

The most widely used fiber laser source in fiber laser marking machine includes IPG, Raycus, Maxphotonics and JPT.

IPG is a German brand and produced in Russia. It has long service life and high stability. But the price is pretty high.

Raycus and Maxphotonics are both Chinese brand. Raycus is in Wuhan and Maxphotonics is in Shenzhen.

Fiber laser marking machine with Raycus laser is the most hot selling machine. Because it is more stable than Maxphotonics.

In the past few years, Raycus occupies a big market. However, since last few years, Maxphotonics has changed their strategy. They cut down their profit to get clients. So you can find that the price of Maxphotonics is much cheaper than Raycus.

JPT laser source is used in MOPA fiber laser marking machine. It is professional in marking black color on anodized aluminum and marking color on stainless steel.

The choice depends on customer’s requirement.

How to choose and distinguish single mode & multi model laser source-Max

How to choose and distinguish single mode & multi model laser source

The excellent characteristics of fiber lasers make more and more end customers pay attention to and consider replacing the original processing methods with fiber laser solutions in metal processing. With the localization of high-power fiber lasers, the cost of various core devices has been greatly reduced. So the selection threshold of high-power lasers has begun to disappear.

Single-mode and multi-mode beam quality comparison

In the cutting application, the focused spot has a great influence on the quality of the cut. The core of the single-mode laser is relatively thin and the beam quality is better than multimode. The energy distribution is Gaussian andthe intermediate energy density is the highest and the three-dimensional map is a sharp circle like the shape of the mountain.

 

The core of a multimode laser is coarser than that of a single mode. The energy distribution is smaller than that of a single mode. The three-dimensional image is an average of a single-mode spot. The three-dimensional image is an inverted cup. From the edge steepness, the multimode ratio is steep, comparing to the single mode.

 

Comparison of 1.5KW single mode and 1.5KW multimode laser with the same power

1mm thin plate cutting speed single mode is 20% higher than multimode. And the visual effect is similar. But from 2mm, the speed advantage is gradually reduced. Starting from 3mm, the speed and effect of high power multimode laser are very obvious. Shown below:

Single mode                                                    multi-mode

 

Therefore, the advantage of single mode is thin plate and the advantage of multimode is thick plate. Single mode and multimode are not worth comparing each other. They are all a configuration of fiber laser. Just like a car, the car is suitable for highway. And the off-road is suitable for mountainous. However, the car can also run on the mountain, and the off-road can also run on the road. Therefore, in the end, the choice of multi-mode or single-mode fiber laser depends on the processing needs of the actual end customer.

 More information of high power fiber laser source will come soon..

How to select suitable fiber laser source – Alex

/in , /by

Fiber laser cutting machine is one of the most popular metal cutting equipment in the market. Fiber laser source is the most important parts. Also we can see there is many different brand laser source in the market. And different suppliers use different brand.

Below is main brand we can find in China market.

  • Raycus

Raycus is the most popular fiber laser source in China market, no matter fiber laser marking machine and fiber laser cutting machine. Also it is the oldest Chinese brand fiber laesr source. and it is the first China brand. It have high quality and stability.

Now not just in China, but also in Europe and USA as most China laser manufacturer promote Raycus laser generator. Compared with IPG laser, its price is much more lower and quality is nearly same quality. It have high cost performance, so it is also very popular in these country.

Raycus laser have good performance on metal cutting, especially on stainless steel and mild steel, also include galvanized sheet, iron sheet.

When laser power lower then 4kw, really it is the best choice.

  • Germany IPG

No doubt IPG is the best fiber laser soruce in the world. Its quality and stability is very high, but its price is also very high. So its market is not big in China market. Only for high power such as 3kw 4kw 5kw 6kw and higher power laser source, it is more popular then other brand.

With IPG laser, it have good cutting performance on stainless steel, mild steel, galvanized sheet cutting.

  • USA nLIGHT

nLIGHT is USA brand fiber laser source, also it have good quality. But its market is not very big in China market as price is more expensive then IPG laser.

Compared with IPG and Raycus laser, nLIGHT laser have big advantage on aluminum cutting. IPG and Raycus have good performance on ordinary metal cutting, such as stainless steel and mild steel. But when cut high reflective material such as aluminum, brass, gold and silver. Other brands can’t do it. nLIGHT laser source have special protective system, so it can cut these high reflective material well.

You can check below working video.

Except above laser source, also there is several other Chinese brand such as MAX, CAS, JPT etc. These brand laser is some yound China company. Compared with Raycus, their price is lower but stability is also lower then Raycus. So many small suppliers use these brand as price is lower. For some low power less then 1000w, also it have good performance. But for high power, we don’t recommend it.
