Generation of cw Radiation of 273mW at 671nm from a Diode-PumpedIntracavity-Doubled Nd:YVO₄ Laser

We have demonstrated a diode-pumped Nd:YVO₄ laser that produced 273mW cw output at 671 nm by using KTP intracavity doubling. The optical-optical efficiency of the all-solid-state red laser was 5.1 %. The maximum output power of the fundamental wave at 1342nm from Nd:YVO₄ was 2.3W with slope-efficiency of 43%.
