Abstract

We present the laser properties of continuous-grown Nd:GdVO4/GdVO4 and Nd:YVO4/YVO4 composite crystals under LD direct pumping. The maximum CW output powers of 20W with a slope efficiency of 74.9% to absorbed pump power and 32W with 82.7% were obtained in Nd:GdVO4/GdVO4 and Nd:YVO4/YVO4 lasers, respectively. To our knowledge, this is the highest slope efficiency obtained in Nd3+ lasers. Furthermore, at the repetition rate of 100kHz, the minimum pulse width of 15.0ns and 12.9ns, the peak power of 11.8kW and 22.4kW were obtained for Nd:GdVO4/GdVO4 and Nd:YVO4/YVO4 lasers, respectively.
