Abstract

Hollow lens duct is a good choice for the coupling system of the large-aperture high power diode arrays. With the help of numerical analyze of three-dimension ray tracing, we developed a computer simulation program for end-pumped LD arrays coupling system. Based on the result of simulation, we build a coupling system for an large-aperture (> 100 cm²) high-power (48kW) LD arrays, which include a hollow lens duct and a homogenizer, and coupled the pumping radiations into a laser crystal of only about 4 cm², coupling efficiency beyond 70% was reached with perfect pumping-uniformity in the gain material.
