Abstract
We present the practical realization of a monolithic single-frequency diode pumped Nd:YVO4/YVO4/KTP microchip laser with birefringent filter operating at 532 nm. Theoretical analysis of the single-mode operation of such a laser configuration is presented. Experimental results are in good agreement with theoretical analysis. 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 ±0.75% and the long-term frequency stability was approximately 3×10−8. The beam has a Gaussian profile and the M2 parameter was below 1.2.
