Abstract

Laser sources have to provide high efficiency, compactness and good reliability to become accepted for applications in fact. Especially in the application-rich shortwave IR spectral region (1.8-3μm) this is a big challenge for lasers on the route to the market. Optically pumped semiconductor disk laser (OPSDL) based on the (AlGaIn)(AsSb) unify preferable features from semiconductor and solid state lasers, therefore they can be an excellent source in this wavelength region [1]. Many applications like gas sensing or LIDAR require single frequency laser operation at a fixed wavelength. To realize this with standard laser setups is quite difficult.
