NOT KNOWN FACTS ABOUT LASER CRYSTAL

Seen stable-condition lasers based on laser crystals are compact and light. Lasers from deep crimson to blue are described. In particular, there have been many stories on Pr3+ doped laser crystals, and ongoing wave lasers all over 490 nm are reached. Ti∶sapphire is the principle obtain crystal for ultrafast lasers. Superintense ultrafast lasers w
