UV, visible and IR active media based on scheelite-type and colquiriite-type fluoride crystals

The experimental results of applying crystal-chemical methods aimed to improving the spectral-kinetic properties of active media based on fluoride crystals with scheelite (LiY1-x LuF4 ) and colquiriite (LiCa1-x AlF6 ) structures doped by rare-earth (Ce3+ and Pr3+ ) and Cr3+ ions are discussed. The energetic and spectral characteristics of lasers based on the active media are presented. The special attention is focused on the prospects of using these lasers in the task of optosensorics, biomedicine, and security systems.
