LITTLE KNOWN FACTS ABOUT LASER CRYSTAL.

Seen sound-state lasers based on laser crystals are compact and light. Lasers from deep pink to blue are actually described. Specifically, there have been a great deal of studies on Pr3+ doped laser crystals, and continuous wave lasers about 490 nm are actually attained. Ti∶sapphire is the main obtain crystal for ultrafast lasers. Superintense ul
