Abstract

This paper demonstrates an eye-safe 1.5 μm continue wave (CW) Er:Yb:YAl3(BO3)4 (Er:Yb:YAB) microchip laser with dual-end pumping. By using a 1.5 mm thick Er:Yb:YAB crystal and 2.5% output coupling transmittance, its maximum output power could reach 4.55 W at the incident power of 15.4 W. This is the largest CW laser output power in the reported Er:Yb:YAB laser. The output laser beam was observed. The beam quality factors M2 in the X and Y directions were 1.65 and 1.71, respectively. The beam quality of the output laser of the CW Er:Yb:YAB microchip laser pumped by dual-end is significantly improved compared to previous works.
