Very high brightness, fiber coupled diode lasers

摘要

We present the latest development of high brightness, diode laser systems at Coherent Direct Diode Systems. Experimental results on diode laser modules with greater than 100 W with beam quality better than 10 mm·mrad will be presented. Through a combination of diode laser emitter improvements and narrow-band (< 10 nm) wavelength combination, we improve the spatial beam quality of diode laser systems significantly. The presentation will show a path that scales these diode laser systems to a kW-class output power from a 100 μm fiber with a single wavelength.
