An 110 W Nd:YVO4 slab laser with high beam quality output

Abstract In this paper we report on experimental results of an end-pumped Nd:YVO 4 slab laser with a hybrid resonator. 110 W output power with beam propagation factor M 2 of 1.3 and 1.5 in two orthogonal directions was obtained. After a spatial filter the typical beam propagation factors at 50 W operation were 1.09 and 1.2.
