Abstract

A diode-pumped passively Q-switched 1066 nm laser with a novel Nd:Gd_0.69Y_0.3TaO₄ mixed crystal was demonstrated for the first time, to the best of our knowledge. A maximum output power of 6.37 W was obtained at an absorbed pump power of 20 W in continuous-wave operation, corresponding to a slope efficiency of 35%. The pulsed Nd:Gd_0.69Y_0.3TaO₄ laser performance was investigated theoretically and experimentally. After optimization by selection of Cr⁴⁺:YAG saturable absorbers, at an absorbed pump power of 16.2 W, the attained minimum pulse width was 22 ns with the pulse repetition frequency of 74 kHz, and the single pulse energy and peak power were estimated to be 28 μJ and 1.34 kW, respectively.
