Abstract
Efficient eye-safe 1.6 μm monolithic laser was realized in a c-cut, 0.7-mm-thick Er3+:Yb3+:YAl3(BO3)4 microchip end-pumped by a quasi-continuous-wave 970 nm diode laser. At incident pump peak power of 20.4 W, a maximum output peak power of 2.6 W with a slope efficiency of 19% was obtained when the waist radius of pump laser beam was 220 μm. The spectra and profiles of output beam of the Er3+:Yb3+:YAl3(BO3)4 monolithic laser were measured. The influences of the waist radius of pump laser beam on the slope efficiency and threshold of the monolithic laser were also investigated.
