摘要：

In this paper, a four-wavelength electro-optic (E-O) Q-switched solid-state laser system was presented. This laser system only use one Nd:YAP laser crystal, which irradiates 1079.5 nm and 1341.4 nm fundamental wavelengths. Both of these wavelength lasers and their second harmonic generation (SHG) compose a four-wavelength Nd:YAP Q-switched laser. The Q-switched output energies of 277 mJ for 1079.5 nm and 61 mJ for 539.8 nm and that of 190 mJ for 1341.4 nm and 51 mJ for 670.7 nm wavelengths were achieved. The pulse durations of 1079.5 and 539.8 nm lasers and that of 1341.4 and 670.7 nm lasers are 20 and 40 ns, respectively. Due to this laser system has the larger chance and convenience for selecting the wavelengths and operation modes by moving a stepping motor and controlling the Q-switched devices, it will broaden applications in the fields of laser cosmetology, dermatotis therapy, material processing and laser display etc.
