Fabrication and characterization of high power diode lasers

High power diode lasers can be used for a lot of applications such as pumping of solid state lasers, direct material processing and printing. The successful use of high power lasers depends on their high efficiency and reliability in combination with a long lifetime. For a further increase in the quality of high power diode lasers the properties of semiconductor laser bars have to be improved as well as the mounting techniques for these bars onto specially designed heat sinks.
