JPT OLP series 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. Compared with Q-switching technology, OLP series fiber laser is more flexible, supporting wider range of frequency adjustment and higher precise control. As compared to JPT M series fiber laser, the MOPA configuration adopts the pulse compensation, which enables minimum pulses deformation, hence makes the peak power of the fiber laser higher.
