Solid state tunable ultraviolet lasers based on fluoride crystals

摘要

The review of experimental results concerning improving the tuning and energy properties of UV lasers based on crystals with the scheelite-type (LiY_(1-x)Lu_xF_4) and colquiriite-type (LiCa_(1-x)Sr_xAlF_6) structures doped by Ce~(3+) and Cr~(3+) ions is presented. The negative effect of pump-induced photodynamic processes in active elements impact on the laser properties and approaches to minimize it are discussed.
