Abstract
Diode-pumped continuous-wave and passively Q-switched pulse Yb:Ca3TaGa3Si2O14 lasers are reported. At an absorbed pump power of 5.4 W, a 1046.4 nm continuous-wave laser with an output power of 3.24 W and a slope efficiency of 63.4% was obtained. When a Cr4+:YAG saturable absorber with an initial transmission of 95% was used, a 1015.2 nm passively Q-switched pulse laser with a repetition frequency of 5.43 kHz, energy of about 73.6 µJ, duration of 35 ns, and peak output power of 2.1 kW was demonstrated.
