Abstract

We report for the first time (to our knowledge) a diode-pumped Nd:YAG laser emitting at 869 nm based on the F 3 / 2 4 I 9 / 2 4 transition, generally used for a 946 nm emission. Power of 453 mW at 869 nm has been achieved in cw operation with a fiber-coupled laser diode emitting 35.4 W at 809 nm . Intracavity second-harmonic generation in the cw mode has also been demonstrated with power of 118 mW at 435 nm by using a BiB 3 O 6 nonlinear crystal. In our experiment, we used a LiNbO 3 crystal lens to complement the thermal lens of the laser rod, and we obtained good beam quality and high output power stability.
