We developed the diode-pumped 6.8-W cw Yb:YAG ceramic laser with the slope efficiency of 82% at 20degC and demonstrated the tunable oscillation of the laser. The tunable range was from 1021.0 to 1083.6 nm.
The diode end-pumped Yb:YAG ceramic laser with high efficiency and high-power was demonstrated. The 5.5-W cw output power was obtained with the slope efficiency of 52%. To the best of our knowledge, this is the highest efficiency of Yb:YAG ceramic laser.
We realized ah 879 nm-LD-pumped Nd:GdVO/sub 4/ laser with maximum slope efficiency of 78%. Thermal conductivity and the thermal lens effect were measured for characterization of the thermal property of the laser.
We succeeded to grow high quality Nd:GdVO/sub 4/ single crystals by the floating zone method. The slope efficiency of 78% was achieved with pumping at 879 nm using a 2 at.% Nd-doped crystal.
