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.

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.
