LITTLE KNOWN FACTS ABOUT LASER CRYSTAL.

Visible stable-state lasers determined by laser crystals are compact and light-weight. Lasers from deep purple to blue have been noted. Specifically, there were plenty of reviews on Pr3+ doped laser crystals, and steady wave lasers close to 490 nm happen to be accomplished. Ti∶sapphire is the key acquire crystal for ultrafast lasers.
