LASER CRYSTAL CAN BE FUN FOR ANYONE

Visible good-condition lasers dependant on laser crystals are compact and light-weight. Lasers from deep red to blue are actually described. In particular, there were lots of experiences on Pr3+ doped laser crystals, and ongoing wave lasers all around 490 nm have been realized. Ti∶sapphire is the primary get crystal for ultrafast lasers.
