Quasi-three-level laser operation of Nd:Y_(0.53)Gd _(0.47)VO_4 mixed vanadate crystal oscillating at 913 nm

摘要

Efficient continuous-wave (CW) laser operation on the ~4 F _(3/2) → ~4 I _(9/2) transition of Nd:Y _(0.53)Gd_(0.47)VO_4, a mixed vanadate crystal, is demonstrated at room temperature employing a compact plano-concave resonator, generating a polarized output power of 0.39 W at 913.2 nm with 2.85 W of pump power absorbed, the optical-to-optical and slope efficiencies being 14 and 25%, respectively.
