LITTLE KNOWN FACTS ABOUT LASER CRYSTAL.

Obvious stable-condition lasers determined by laser crystals are compact and light-weight. Lasers from deep red to blue have been reported. Primarily, there were a lot of studies on Pr3+ doped laser crystals, and continuous wave lasers all-around 490 nm are already achieved. Ti∶sapphire is the most crucial obtain crystal for ultrafast lasers. Sup
