Continuous-wave and passively Q-switched pulse Yb:Ca3TaGa3Si2O14 lasers at 1.0?m

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 mu J, duration of 35 ns, and peak output power of 2.1 kW was demonstrated.(c) 2022 Optica Publishing Group under the terms of the Optica Open Access Publishing Agreement
