Abstract
A diode-pumped Cr4+:YAG passively Q-switched 1066â¯nm Nd:GdTaO4 laser was demonstrated for the first time to the best of our knowledge. The crystal characteristics of Nd:GdTaO4 was presented. A maximum output power of 3.03â¯W was obtained at an absorbed pump power of 12.6â¯W in the continuous-wave (CW) operation, corresponding to a slope efficiency of 28%. The pulsed Nd:GdTaO4 laser performance was investigated theoretically and experimentally. After optimization selection of Cr4+:YAG saturable absorbers, at an absorbed pump power of 12.6â¯W, the obtained minimum pulse width was â¼22â¯ns with the pulse repetition frequency of 65â¯kHz, and the single pulse energy and peak power were estimated to be 18.1â¯Î¼J and 0.79â¯kW, respectively. The laser performance can be further improved when a Nd:GdTaO4 crystal with better quality is used.
