Optically pumped semiconductor lasers at 505nm in the power range above 100mW

Lasers based on optically pumped semiconductors (OPS) offer unique capabilities in both wavelength tailoring and power scaling compared to traditional solid-state lasers. In particular, these lasers can be designed in wavelength to realize for instance 505nm, which enables excitation of two fluorescent dye chemistry sets originally established by 488 and 514 nm legacy argon lasers. Highly efficient intra cavity frequency doubling of an 1010nm OPS yields over 100 mW of output power at 505 nm. In this paper we will present a brief background on OPS technology. We will then discuss specifics of the 505 nm laser and present both performance and reliability data for this laser.
