Spectroscopy and femtosecond laser performance of Yb3+:YAlO3 crystal.

We report what we believe to be the first demonstration of cw and passively mode-locked Yb(3+):YAlO(3) (Yb:YAP) laser operation under diode pumping. Spectroscopic properties of a 0.6 at.

Efficient 1 W continuous-wave diode-pumped Er,Yb:YAl3(BO3)4 laser.

We report the spectroscopy and high-power continuous-wave (CW) diode-pumped laser operation of Er:Yb:YAl3(BO3) crystal. Absorption and stimulated emission spectra, emission lifetimes, and efficiency of energy transfer from Yb3+ to Er3+ ions were determined. A CW Er:Yb:YAB laser emitting at 1602, 1555, and 1531 nm with output power as high as 1W and slope efficiency up to 35% was demonstrated.

Diode-pumped Yb,Er:glass laser passively Q switched with a V3+:YAG crystal.

Saturable-absorber Q switching of a diode-pumped erbium-doped glass laser at 1.54 microm with a V:YAG crystal has been demonstrated. An average output power of 30 mW with Q-switching efficiency of 37% and pulse duration of 350 ns have been obtained.
