摘要	The phase matching BBO was utilized as a frequency-doubling crystal to produce continuous ultraviolet laser with a central wavelength of 261.37 nm and the blue laser diodes with different wavelengths were used to pump the Pr:YLF in different ways. Two different wavelength blue laser diodes (444 nm and 469 nm) were used to pump Pr:YLF separately with V-shaped folded cavity structure. The two blue laser diodes were combined as the pumping source to increase the pumping power while retaining the high polarization absorption efficiency of Pr:YLF crystal after optimization. The length of Pr:YLF crystal was 5 mm, the doping concentration was 0.5%. Continuous 261.37 nm ultraviolet laser output with the maximum output power of 245 mW was obtained when the pumping power was 2 800 mW. The optical-to-optical efficiency was about 8.75%. 2020, Editorial Board of Journal of Infrared and Laser Engineering. All right reserved.
