3.2 STJ-LP-Series MOPA Fiber Lasers

STJ-LP-Series Fiber Lasers adopts MOPA (Master Oscillator Power Amplifier) structure, diode laser as seed light, and fiber based power amplification. This laser integrates independence adjustment of pulse width and frequency, to make sure a constant pulse energy output, which provides a good combining solution to the requirements of high power laser source and high marking speed.

The extremely flexible pulse width and frequency adjustment, which plays a significant impact on colour formation, enables colour or silver shining marking on stainless steel.

3.3 STJ-M1-Series MOPA Fiber Lasers

STJ-M1-Series MOPA 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, while the peak power of the fiber laser can be well maintained. This feature is crucial for material processing applications, such as laser marking. Besides, its good pulse width tunability enables minimum pulses deformation, increases the

thresholds of nonlinearities, and hence makes the laser more reliable and robust.

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.

5. STM Series Nanosecond Pulsed Fiber Lasers

775nm pulsed fiber of Nanosecond Pulsed Fiber Lasers have been designed to allow users flexibility in their application refinement. With user selectable pulse-widths and repetition rates, these lasers put more options into the hands of the user than traditional lasers with fixed parameters. In addition, the ability to externally trigger pulses on some of the models make these laser an extremely flexible tool.

Based on an all-fiber laser cavity design and offering excellent beam quality and wall plug efficiency, these compact air-cooled lasers are an ideal choice for your application.ns fiber laser

6. 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.

beam combiner module

The beam combiner module STM-1064/650 is designed for combining 1064nm and 650nm laser beams. The matched red diode is 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.
