A Laser-Diode-Pumped 7.36W Continuous-Wave Nd:YVO₄ Laser At 1342nm

An efficient and high-power diode-laser single-end-pumped Nd:YVO₄ laser with cw emission at 1342nm is presented. With a crystal single-end-pumped by a fibre-coupled diode laser, an output power of 7.36W is obtained from the laser cavity of concave-convex, corresponding to an optical-to-optical conversion efficiency of 32.8%. The laser is operated in TEM₀₀ mode with small rms noise amplitude of 0.3%. This represents, to the best of our knowledge, the highest power obtained from a diode-laser single-end-pumped Nd:YVO₄ cw laser at 1342nm so far.
