Abstract

In this paper the development and optimization process of single frequency, diode pumped Nd:YVO₄/YVO₄/KTP microchip laser operating at 532nm is presented. A birefringent filter formed by beam displacer (undoped YVO₄ crystal) and KTP crystal was used to obtain single mode operation. As a final result of optimization miniature, monolithic laser resonator was elaborated. The laser generated Gaussian beam with quality better than M²<1.2 and maximum single frequency output power at the level of 160mW @ 532 nm. The optical to optical efficiency (532nm to 808nm) was at the level of 16,8% at the maximum single frequency output power.
