What is Mopa laser marking machine?—Tony

What is Mopa laser marking machine?

What is Mopa laser marking machine?  As a sales person, for this question, I was often asked. So what is the Mopa laser on earth? I will give all the persons who read my blog a best answer.

Mopa principle

Mopa is a name of laser source type. The difference between Mopa and regular fiber laser marking machine is not too big. Because, Mopa is fiber laser in principle. But Mopa’s pulse is adjustable. But for regular fiber laser machine, the laser source’s pulse is fixed. However both of them are fiber laser, the only difference in principle is whether it adjust the pulse.

Thus, why people design a laser source that could adjust laser pulse? What is it used for?

Since people can adjust the laser pulse, then it achieves multi-color marking on metal materials.

Like the video below, We used Mopa to coloring mark stainless steel.

Mopa Functions

But as you can see, the speed of color marking is very slow.  So what other advantage make Mopa still occupy the laser marking market?

At present, the aluminium oxide is a general materials for smart phone case. The Mopa laser is very good to do it. If use the regular fiber laser source to mark aluminium oxide. It won’t mark black on it. You will see it is the grey color if you see at the front.  But if you see from two sides,  it will turn to black. And you can feel burr on the material surface. But using Mopa laser, these questions will be gone.

And  If you bought a Mopa marking machine. You just set the pulse be fixed. Then the machine will become a fiber laser marking machine. Then it will enhance the speed of marking. So the Mopa laser machine could become a regular laser marking machine. So that is why, price of Mopa will higher than fiber laser. Mopa laser machine has more functions.

In short, XT laser use the mopa laser source from JPT and Raycus in general. If you do interested in our machine.

Q-switch and mopa marking machine-Wendy

Industrial fiber lasers have been the largest focus in the laser industry over the past few years.  The development of domestic fiber lasers has been rapid.  In the sheet metal cutting and marking applications have made considerable progress in the promotion of processing industry upgrading. To help customers achieve efficient, energy-saving production shows unparalleled advantages.

At present, the types of fiber lasers used in industrial marking mainly include Q-switched lasers. And Mopa lasers, which occupy most of the marking market share. But there is a misunderstanding in the market. That the Mopa laser can completely replace the Q-switched laser in many applications.

In fact, otherwise, in order to help customers understand the two different technologies of laser.  To solve different customer marking requirements, we chose the joint product laser Q-switched laser and Mopa laser as the experimental object.  Made some simple and simple analysis. To help customers find suitable for their own marking requirements of the model.

Comparison of parameters between Q-switched lasers and Mopa lasers

MOPA (Power amplifier master oscillator power-amplifier) and Q-switched fiber lasers are widely used in many fields.  Such as electronic products, machinery and packaging. As the mainstream lasers for marking applications in the market. It is quietly replacing traditional processing.
Also Used in marking processing.  What are the differences and advantages and disadvantages?
From the parameter comparison that the Mopa laser parameter is flexible and the adjustment range is big, the use of the kill pulse width, the high frequency parameter, the heat duration is short, the main application in the alumina black, the customer can adjust the power, the frequency parameter to achieve own desired effect.
Because of the higher pulse frequency of Mopa ray Laser. The marking position is very small or overlapping during marking. And the shading will be very uniform and delicate. Because the single pulse energy is low. The material is not easy to produce thermal deformation once the thin plate is treated. After the development of Mopa with narrower pulse width (electric control to do light pulse in dozens of picosecond) as the direction, the heat duration is shorter, marking delicate degree greatly improved.

Comparison of application of Q-switched laser and Mopa laser in marking

Mopa Laser, Q-switched laser repetition frequency is low. The fine processing of the material will be less than Mopa. However, because of the single performance parameters of Q-switched lasers. The use of adjustment will be more convenient and rapid. In the plastic material black dozen gray aspect. The adjustment q although is inferior to the mopa processing fine. But wins in the speed quicker, for the request not high processing may use the Q-switched laser to raise the production efficiency. In the aspect of the deep carving of metallic materials. Q-switched fiber lasers, because of their high single pulse energy. It can be used in depth engraving or metal surface rust removal.  Mopa laser in wide pulse width amplification because most of the energy trailing useless. It can not be used effectively. It’s marking strength is deficient. In view of the current market expectations, Q-switched lasers will be high power. It will be also the high energy development to meet the requirements of material processing.
