Abstract

A passively Q-switched dual-wavelength laser with pulsed LD coaxial end-pumped configuration was demonstrated. A theoretical model was built to simulate the dynamic process of the pulsed LD coaxial end-pumped dual-wavelength laser. Experimental verifications were carried out based on Nd:YAG/Nd:YAP crystals. When the reflectivity of the output mirror and the initial transmission of the saturable absorber were both 50%, the maximum output single-pulse energy of pulsed-pumped passively Q-switched dual-wavelength laser was 304 μJ, which was obviously enhanced compared with that in the CW pumping.
