MOPA fiber laser marking machine pulse width adjustable pulse fiber laser diode laser oscillator and high-power fiber amplifier structure. Emission wavelength of about 1060nm and peak power of more than 8KW periodic pulse sequence. The operating parameters are set via the 25Pin control interface. Its compact, wrinkled surface, stand-alone, easy to use design style, can be directly integrated into the user's equipment, and can be used as an ideal industrial laser marking high power laser source, which is mainly used in low reflective materials Paper, etc.) marking, and for some of the metal reflectivity is not high marking.
