Diode-pumped continuous-wave Nd:LuV[O.sub.4] laser emitting at 1089 nm based on the [sup.4][F.sub.3/2]-[sup.4][I.sub.11/2] transition

We present what is, to the best of our knowledge, the first diode-pumped Nd:LuVQ laser emitting at 1089 nm, based on the [sup.4][F.sub.3/2]-[sup.4][I.sub.11/2] transition, generally used for a 1066 nm emission. A power of 8.7 W at 1089 nm has been achieved in continuous-wave (cw) operation with a fiber-coupled laser diode emitting 18.7 W at 809 nm. Intracavity second-harmonic generation in cw mode has also been demonstrated with a power of 3.6 W at 544.5 nm by using a Li[B.sub.3][O.sub.5] nonlinear crystal. OCIS codes: 140.3530, 140.3480, 140.3515.
