Abstract :
In this paper, we present a carefully elaborated layer design for semiconductor disk lasers. Experimental results of devices mounted on simple copper heat spreaders reveal a conversion efficiency of 54% at 13.2 W for 970-nm wavelength laser emission and a differential quantum efficiency of 73%.
