Unique high-power fiber laser technologies

Continuous wave (CW) fiber laser systems with output powers in excess of 500 W with good beam quality have now been demonstrated, as have high energy, short pulse, fiber laser systems with output energies in excess of 1 mJ. Fiber laser systems are attractive for many applications because they offer the promise of high efficiency, compact, robust systems. We have investigated fiber lasers for a number of applications requiring high average power and/or pulse energy with good beam quality at a variety of wavelengths. This has led to the development of a number of custom and unique fiber lasers. These include a short pulse, large bandwidth Yb fiber laser for use as a front end for petawatt class laser systems and a narrow bandwidth 0.938 mu m output Nd fiber laser in the > 10 W power range.
