Abstract

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.
