主　　题：high-power ultraviolet laser Pr^(3+):YLF tunable ultraviolet laser 

摘      要：High-power continuous-wave ultraviolet lasers are useful for many *** ultraviolet laser sources,the wavelength switching capability and compact structure are very important to extend the applicability and improve the flexibility in practical *** this work,we present two simple and relatively compact schemes by laser diode pumping to obtain a watt-level single-wavelength 348.7-nm laser and discrete wavelength tunable ultraviolet lasers around 349 nm(from 334.7 to 364.5 nm)by intracavity frequency doubling based on Pr^(3+):YLF andβ-BBO *** maximum output power of the single-wavelength 348.7-nm laser is 1.033 *** output powers of the discrete wavelength tunable lasers are at the level of tens of milliwatts,except for two peaks at 348.7 and 360.3 nm with output powers of approximately 500 *** addition,simulations are carried out to explain the experimental results and clarify the tuning mechanisms.
