LITTLE KNOWN FACTS ABOUT LASER CRYSTAL.

Visible solid-state lasers based upon laser crystals are compact and light-weight. Lasers from deep crimson to blue have already been reported. Primarily, there were a lot of stories on Pr3+ doped laser crystals, and steady wave lasers around 490 nm are already obtained. Ti∶sapphire is the principle acquire crystal for ultrafast lasers.
