Abstract :
In this work we present spectroscopy, continuous-wave (cw) and Q-switched laser operation of Er,Yb-codoped YAl3(BO3)4 (Er,Yb:YAB) crystal under diode pumping. Single crystal of Er(1 at.%),Yb(11 at.%):YAB with dimensions of 15times15times20 mm was grown by the TSSG method using K2Mo3O10 based fluxes. The concentration of the dopants was measured by microprobe analysis. In conclusion, spectroscopic properties and CW and passively Q-switched diode-pumped laser performance of Er,Yb-codoped YAB crystals have been characterized. The results of laser experiments with more powerful diode pumping and cw output power exceeding 300 mW will be presented at the conference. Laser experiments were performed with a nearly hemispherical cavity consisting of 50-mm radius-of-curvature output coupler and plane high reflector.
