Paper Abstract

In this paper the practical realization of a single frequency, monolithic diode pumped Nd:YVO4/YVO4/KTP microchip laser operating at 532nm is presented. The optical crystals formed the laser resonator were bonded together with UV curable adhesive. Elementary analysis of the single mode operation of such a laser configuration is presented. Period of the Lyot filter, temperature mode-hop free range of designed laser was calculated. The single frequency operation has been obtained in a birefringent filter, where an YVO4 beam displacer acts as an ideal polarizer. We have obtained stable single frequency operation, in the two spectral ranges around 1064nm. Investigation of the single frequency operation range shifting with pump power was done. Experimental results are in good agreement with theoretical analysis. The laser operated with output power up to 85mW at 532nm. The total optical efficiency (808nm to 532nm) was 9%. The beam has a Gaussian profile and the M2 parameter was at the level of 1.2.
