3.3 STJ-M7 Series MOPA Fiber Lasers

STJ-M7 series high power pulsed fiber lasers make use of master oscillator power amplifier (MOPA) configuration, and show excellent laser performance as well as high level of temporal pulse shaping controllability. As compared to the Q-switching technology, the pulse repetition frequency (PRF) and pulse width can be controlled independently in MOPA configuration, through adjusting different combination of the above parameters, the peak power of laser can be well maintained. These lasers are suitable for more material processing which Q-switch limited. The higher output power makes its advantages especially in high speed marking applications.

Application Advantages

  • Scribing, drilling

  • Surface treatment

  • Sheet metal cutting, welding

  • Marking on fly

  • Metal surface processing, peeling coating
