Packaging and Characterization Equipment for High-Power Diode Laser Bars and VCSELs

摘要

High-power diode lasers serve as small and highly efficient laser-beam sources. Their output power has been increased steadily over the recent years. Nowadays, the output power of one diode laser bar is sufficient for many different applications such as pumping of solid state lasers, direct material processing, medical applications or printing. The successful use of high-power diode lasers depends on their high reliability in combination with a long lifetime. For a further increase in the quality of high-power diode lasers the properties of semiconductor lasers have to be improved as well as the cooling and mounting techniques for these bars onto specially designed heat sinks.
