1085 nm Nd:YVO_4 laser intracavity pumped at 914 nm and sum-frequency mixing to reach cyan laser at 496 nm

摘要

We present for the first time a Nd:YVO_4 laser at 1085 nm intracavity pumped at 914 nm by a Nd:YVO_4 laser. We obtained intracavity powers of 57 W at 914 nm and 62 W at 1085 nm. Using type-I critical phase-matching LiB_3O_5 (LBO) crystal, a cyan laser at 496 nm is obtained by 914 and 1085 nm intracavity sum-frequency mixing. The maximum laser output power of 142 mW is obtained when an incident pump laser of 19.6 W is used.
