✦ Synopsis

We report a diode-pumped Nd:YVO 4 laser emitting at 880 nm based on the 4 F 3/2 -4 I 9/2 transition for the first time. A power of 1.13 W at 880 nm has been achieved in continuous-wave operation with a fiber-coupled laser diode emitting 28.6 W at 808 nm. Furthermore, intracavity secondharmonic generation in continuous-wave mode has also been demonstrated with a power of 233 mW at 440 nm by using a BiB 3 O 6 (BiBO) nonlinear crystal. The fluctuation of the blue output power was better than 2.3%. The beam quality M 2 value is 1.2. Output power at 880 nm, W 0.8 0.6 0.4 0.2 0 1.0 1.2 Output power at 440 nm, W 0.30 0.25 0.20 0.

We describe the output performances of the 942 nm 4 F 3/2 → 4 I 9/2 transition in Nd:GSAG under diode-laser pumping. An end-pumped Nd:GSAG crystal yielded 3.7 W of continuous-wave output power for 17.8 W of absorbed pump power. The slope efficiency with respect to the absorbed pump power was 23.4%.
