Paper Abstract

We attach micro-cylindrical lenses with D/f' equals 4/3 to 300 W Q-CW LD array, pre-compressing the divergent angle in fast-axis plane from 40 degree(s) to 9.6 degree(s). Then we use lens duct as optical coupler in LD array end-pumped Nd:YAG laser. The transfer efficiency is 90%, and well convergent effect is also obtained near the output face of lens duct. At last, we get 37.9% light-light conversion efficiency of 1.06 micrometers light at 1% duty factor, and the output beam is good.
