Numerous markets for near-infrared, high-power, multi-mode diode lasers as a direct thermal source have emerged in recent years due to improved device price-to-performance ratios. Diode lasers are currently used as replacement sources in many thermal applications requiring a non-contact heat source and are also utilized in the development of new processes. Industrial applications include welding, epoxy curing, soldering, hardening, sintering, cutting and materials processing. They are also used in graphics, pumping, illumination, and a variety of medical applications. These devices provide high electrical-to- optical efficiency, are compact, virtually maintenance free, easily integrated, and are cost effective.
