Abstract
Laser diode arrays are currently replacing flashlamps as optical pumping sources for high power solid state laser systems. With this advanced technology comes the challenge of transferring the energy from these sources to the laser material. Coupling the energy emitted by these arrays is important as simultaneously it determines the laser's efficiency and beam quality. Nonimaging reflectors offer several advantages over coupling schemes using imaging devices for this application. Various tradeoffs affecting the laser's output are discussed, while model-predicted and experimental deposition profiles will be presented.
