Diode-pumped Nd:YVO_4 laser emitting at 1074 nm based on the F _(3/2)~4- i _(11/2)~4 transition

摘要

We report a diode-pumped Nd:YVO_4 laser emitting at 1074 nm, based on the F _(3/2)-~4 I _(11/2)~4 transition, generally used for a 1064 nm emission. A power of 323 mW at 1074 nm has been achieved in continuouswave (CW) operation with a fiber-coupled laser diode emitting 18.2 W at 808 nm. Intracavity second-harmonic generation in CW mode has also been demonstrated with a power of 18 mW at 537 nm by using a LiB_3O_5 (LBO) nonlinear crystal.
