Abstract

A continuous-wave (CW) dual-wavelength laser with coaxial diode end-pumping configuration is demonstrated. A theoretical model was built to simulate the CW output power process of the dual-wavelength laser generation. The experiment was performed with Nd:YVO4/Nd:YAP composite laser crystals. The continuous-wave output power reached 5.28 W under the maximum LD pump power of 15 W, corresponding to optical-optical conversion efficiency of 35.2%. The power ratio between 1064 nm and 1080 nm could be tuned by varying the pump wavelength to balance the gains in two laser crystals.
