All-Solid-State Multi-Wavelength Laser System from 208 to 830 nm

Four-wavelength lasers from near-infrared to deep-ultraviolet range, 532, 830, 415 and 208 nm, have been developed in one all-solid-state laser system. The laser system is pumped by a diode-Q-YLF laser at 532 nm, a Ti:sapphire laser and the nonlinear second-harmonic-generation crystals LBO and BBO are used to generate different wavelengths. Maximum average powers (repetition rate 1 kHz) of 1.1 W at 830 nm, 380 mW at 415 nm, and 39 mW at 208 nm are obtained when the pumping power is 3.6 W. The main characteristics of this system are presented.
