THE BASIC PRINCIPLES OF LASER CRYSTAL

Obvious good-point out lasers based upon laser crystals are compact and light-weight. Lasers from deep pink to blue happen to be noted. Specifically, there were lots of experiences on Pr3+ doped laser crystals, and continual wave lasers around 490 nm are already reached. Ti∶sapphire is the primary gain crystal for ultrafast lasers.
