Paper Abstract

DILAS Diode Laser, Inc. continues to improve and optimize high-brightness fiber-laser pump modules. Highlights include a 330W module weighing in at 300 grams, achieving greater than 55% electrical-to-optical efficiency at the operating power from a 225micron/0.22NA fiber and a power-scaled version capable of >600 W, >50% efficiency and weighing in at less than 400 grams. The macro-channel coolers enabling these modules eliminate the need for microchannels and deionized water and reduce pressure drop across the system. A road map to modules with >900W of output power will also be presented.
