Abstract
We have developed degradation-free tunable ultraviolet laser. A growth of 7-cm diameter Ce3+:LiCaAlF6 (Ce:LiCAF) boule succeeded in CF4 atmosphere by the Czochralski method. Chirped-pulse amplification (CPA) in the ultraviolet region is demonstrated by use of a large-sized, broadband Ce:LiCAF laser medium. A coaxially pumped, large-aperture ultraviolet power-amplifier is also demonstrated for a terawatt-class ultraviolet CPA laser system. Future scaling of this Ce:LiCAF laser system will make available a new category of high-peak-power lasers in the ultraviolet region.
