The 20-100W Q-Switched Pulse Fiber Laser Series developed by Raycus is the industrial marking and micromachining laser. This series pulse laser has high peak power, high single-pulse energy and optional spot diameter and can be widely applied in the fields, such as marking, precision processing, graphic engraving of non-metal, gold, silver, copper and aluminum with altitude stress resistance, stainless materials without altitude stress resistance. Its marking process features lower cost and more stable performance compared with traditional laser.
