摘要

A microchannel-cooler package under development would eliminate many of the concerns of older-style microchannel packages and promises a roughly 30percent improvement in cooling ability for laser-diode bars. Laser manufacturers have recently made significant improvements to the amount of output power that can be produced by high-efficiency laser-diode bars. Optical output powers greater than 120 W continuous wave (CW) from a single diode bar when packaged on a microchannel cooler have been demonstrated. These high powers test the limits of epitaxial structure design, dielectric coating design, and packaging techniques. While epitaxial and dielectric coating designs have made significant advances recently, many suppliers and consumers of high-power bars have not addressed the packaging developments necessary to take advantage of improved bar performance. Fortunately, new diode package designs are being implemented to provide superior technical solutions while maintaining the size and performance characteristics of traditional diode heat exchangers.
