Paper Abstract

We have developed a single-emitter multi-mode laser-diode-pump platform for high efficiency, brightness and high reliability in a small form factor. This next-generation package is scalable to higher optical power and offers a low-cost solution for industrial applications, such as fiber lasers, graphic arts and medical. The pump modules employ high coupling efficiency, >90%, high power-conversion efficiency, >50%, and low thermal resistance, 2.2°C/W, in an electrically-isolated package. Output powers as high as 18W have been demonstrated, with reliable operation at 10W CW into 105μm core fiber. Qualification results are presented for 0.15NA and 0.22NA fiber designs.
