Abstract
In this paper miniature, monolithic single frequency solid state laser operating at 532 nm is presented. Developed Nd:GdVO4/YVO4/KTP consist of three crystal bonded together with a UV adhesive. The single frequency operation was obtained in wide temperature range from 17°C to 27°C. The laser operated with output power up to 90 mW at 532 nm. The total optical efficiency (808 nm to 532 nm) was 9.5%. Power stability was at the level of ±0.8% and the long term frequency stability was approximately 3⋅10−8. The beam has a Gaussian profile and the M2 parameter was below 1.1.
