Abstract

A Ho:YVO4 laser double-pass-pumped with a 1.91 μm wavelength-stabilized laser diode is presented in this paper. The maximum output power was up to 8.7 W, with a wavelength of 2052.4 nm and a slope efficiency of 37.4%. The M2 factors in the x and y directions were 1.8 and 1.6 at the maximum output power, respectively.
