High Power Pulsed MOPA Fiber Laser Source 500W
Product introduction
High power 500W MOPA laser is a pulsed laser with high beam quality and high-power laser output that uses a low-power laser with high beam quality as the seed light source, and achieves high beam quality and high-power laser output through a single-stage or multi-stage fiber amplification system. Compared with Q-switched fiber lasers, the pulse frequency and pulse width of high power MOPA fiber lasers are independently controllable, with a wide selection range of pulse widths, and can maintain a better pulse waveform. Welding, precision cutting and other applications.
