We report a design of a cerium-doped lithium calcium hexafluoro aluminumate (Ce:LiCaAlF6 , Ce:LiCAF) laser resonator based on total internal reflection (TIR). This TIR configuration is established by placing the Ce:LiCAF crystal between two calcium fluoride (CaF2 ) Pellin-Broca prisms. The laser resonator exhibits a 289-nm emission with spectral linewidth and pulse duration. Results show that the present configuration can be a high Q-factor, easy-to-use, broadband prism resonator suitable as a laser oscillator not only in the ultraviolet (UV) region but also down to vacuum ultraviolet (VUV) wavelengths where alignment is restricted to vacuum environments.
