摘要：

We present an Yb:KY(WO4)(2) (Yb:KYW) laser emitting at 981 nm intracavity pumped by a 912 nm diode-pumped Nd.GdVO4 laser. A 808 nm diode laser is used to pump the Nd.GdVO4 crystal emitting at 912 nm, and the Yb.KYW laser emitting at 981 mn intracavity pumped at 912 mn. This configuration enabled us to indirectly diode-pump this ytterbium doped crystal, and to obtain 1.12 W output power at 981 nm for 19 6 W of incident pump power at 808 nm. Furthermore; ultracavity second harmonic generation has also been demonstrated with a power of 106 mW at 490.5 nm by using a LBO nonlinear crystal.
