FASCINATION ABOUT LASER CRYSTAL

Seen sound-state lasers based on laser crystals are compact and light. Lasers from deep pink to blue happen to be described. Specially, there have been a great deal of reviews on Pr3+ doped laser crystals, and steady wave lasers about 490 nm are reached. Ti∶sapphire is the most crucial gain crystal for ultrafast lasers.
