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.

7. Beam Combiner Modules

We also provide beam combiner modules (or called as red aiming module), which is designed for the use with the fiber lasers (or Nd:YAG lasers etc). Inside there is a beam combiner. A red diode is vertically fixed and the fiber laser beam horizontally goes through the module.

The beam combiner module STM-1064/650 is designed for combining 1064nm and 650nm laser beams. The matchedred diodeis ST-SD650-5G1 and the beam combiner is the diemsnion Φ20x1.5mm (or Φ20x2mm, Φ20x3mm etc) such as STJ-1064-BC-20-2. For other laser wavelengths, just select other beam combiners and the beam combiner modules at other wavelengths are available upon request. Please contact us for more information.
