The most popular way of achieving power scalability is the “MOPA” (Master Oscillator Power Amplifier) approach. The “MO” produces a highly coherent beam, and an optical “A” is used to increase the power of the beam while preserving its main properties. The “MO” has no need to be powerful, and has no need to operate at high efficiency because the efficiency is determined mainly by the “PA”. The combination of several laser amplifiers seeded by a common “MO” is essential concept of the High Power Laser Energy Research Facility.
● Color marking on stainless steel: With mopa fiber laser marking machine, we can do many beautiful color on stainless steel, such as red, blue, pink, green etc.
● Black marking on anodised aluminium: Q-switched fiber laser marking machine can only do ordinary marking on anodised aluminium. With mopa fiber laser marking machine we can do black marking on anodised aluminium easily.
● Phone case: We know most phone case are anodised aluminium material now. such as Iphone, Ipad, HUWWEI, Samsung etc. Now most of them use mopa laser marking machine mark serial number, IMEI number, logo etc.
● White marking on black plastic & black marking on white plastic.
1. 2ns – 200ns ultrawide adjustable pulse width allows wide application range of materials
2. Pulse repetition rate of 1-1000kHz achieves better performance on plastics and other sensitive materials
3. Short pulse duration enables quick black marking of aluminum.
4. Excellent beam quality, no deformation or paint peeling on thin plate
5. First pulse availability and quicker pulse response speed.
