Raycus RFL-QCW75/750 75W QCW Fiber Laser

QCW Fiber Lasers
Multi-module continuous fiber laser Raycus Q-switched pulsed fiber laser has the advantages of high peak power, high single pulse energy, and optional spot diameter. It can be widely used in marking, precision machining, graphic engraving, etc. of non-metallic, gold, silver, copper, aluminum resistant to plateau stress It can also be applied to stainless steel materials that are not resistant to plateau stress.

The quasi-continuous fiber laser developed by Raycus Laser has higher electro-optical conversion efficiency, better beam quality, and less maintenance cost. It is a perfect substitute for the existing lamp pumped YAG laser. Because of the diversified compatibility of this series of products, most YAG systems can use this product with a simple modification. It is an ideal choice for industrial applications requiring long pulse width and high peak values such as spot welding, seam welding and drilling.


With continuous and pulsed modes, peak power up to 15000W, extremely stable output performance, excellent beam quality, output length, optional air-cooled/water-cooled heat dissipation
