Abstract

A highly efficient TEM₀₀ mode 1063 nm Nd:GdVO₄ laser is accomplished with a simple plano-plano resonator. The laser threshold pump power is 856 mW. The maximum laser power of 2.05W is achieved when the pump power is 3.76 W, corresponding to a slope-efficiency of 70% to absorbed pump power. The quality of the output beam is analyzed with a laser beam quality analyzer. The perfect laser beam quality is partially attributed to the short cavity length of 11 mm and the precise temperature control to the Nd:GdVO₄ crystal. The output laser central wavelength is 1063.1 nm with a laser linewidth of 0.06 nm.
