Abstract

A mixed laser crystal of Nd_0.0053(Gd_0.42Y0.58)_0.9947VO₄ has been successfully grown by the Czochralski method. The special properties of this crystal have also been measured. Formed with a simple concave-plano resonator, passive Q-switching operation of a diode-pumped Nd_0.0053(Gd_0.42Y_0.58)_0.9947VO₄ laser with Cr⁴⁺:YAG has been demonstrated. For Q-switched operation, the maximum average power was measured to be 1.11W with the corresponding repetition rate of 10 kHz, the pulse width of 10 ns when the initial transmission of Cr⁴⁺:YAG crystal was 60%. Meanwhile, the largest pulse energy of 111 μJ and the highest peak power of 14.61 kW were obtained.
