Thulium Fiber Laser Pumping

As applications for thulium fiber lasers such as laser lithotripsy, clear plastic welding, and IR countermeasures continue to be developed, leading manufacturers are choosing nLIGHT 793nm semiconductor lasers as their pump source. nLIGHT’s proven reliability of the element product family across industrial and medical industries demonstrates a platform that can be trusted.

Element diode modules are available at 793nm with power levels up to 190 W in 200 µm fiber or 130 W in 105 µm fiber. These products are normally rated for continuous wave operation, but can also be overdriven if operated in a quasi-continuous wave (QCW) model. 

nLIGHT is one of the few vertically integrated high-power diode manufacturers in the world. By controlling the design and manufacturing of the chip, nLIGHT is able to offer a product that leads the market in both brightness and lifetime.
