摘要：Diode-end-pumped high-power Nd:GdVO4lasers at 1083nm are presented. The maximum continuous-wave output power was 10.1W with an optical conversion efficiency of 31.3%. For acoustooptic (AO) Q-switched operation, the largest pulse energy, shortest pulse width, and highest peak power were 111 μJ, 77 ns, and 1.44 kW, respectively. By decreasing the 1063nm transmission of the output coupler, we also achieved efficient CW dual-wavelength operation at 1083 and 1063 nm. Their total output power reached 6.7 W, and the optical conversion efficiency reached 31.6%. These lasers have special requirements in the treatment of facial telangiectasia. © 2012 The Japan Society of Applied Physics.
