Zhang, Z. Wang, S. Luo, G. Wang, Y. Zhu, Z. Xu, C. Chen] Fourth harmonic generation of a tunable Ti:sapphire laser with a repetition rate of 80MHz and pulse duration ∼150 fs has been realized in a single pass with an RbBe2BO3F2 crystal for the first time. A high average power was obtained which was tunable throughout a wide range from 180 to 232.5nm. The output power over the whole range exceeded 2mW, the highest being 43.3mW at 202.5nm. Moreover, deep-ultraviolet output with powers above 75mW was obtained at 193.5 and 200nm under a stronger focusing condition. This is the first attempt at the generation of tunable deep-ultraviolet light without using a KBBF crystal, which is very difficult to grow due to its strong layering tendency, and our attempt may provide new opportunities for the development of all-solid-state deep-ultraviolet coherent light sources.
