Abstract
We present what is, to the best of our knowledge, the first experiment of intracavity pumping at 914 nm of an Yb:SFAP crystal emitting at 985 nm on the three-level laser transition. This configuration enabled us to indirectly diode-pump this ytterbium doped crystal, and to obtain 1.4 W output power at 985 nm for 20 W of incident pump power at 808 nm. Intracavity second harmonic generation has also been demonstrated in a KNbO3 crystal with a total of 120 mW linearly polarized output power at 492.5 nm on two output beams.
