FASCINATION ABOUT LASER CRYSTAL

Noticeable strong-point out lasers based on laser crystals are compact and lightweight. Lasers from deep crimson to blue are already noted. Specially, there were a great deal of experiences on Pr3+ doped laser crystals, and continual wave lasers about 490 nm are attained. Ti∶sapphire is the main achieve crystal for ultrafast lasers.
