5 SIMPLE TECHNIQUES FOR LASER CRYSTAL

Seen sound-point out lasers according to laser crystals are compact and lightweight. Lasers from deep red to blue have already been claimed. Specifically, there have been lots of studies on Pr3+ doped laser crystals, and continual wave lasers close to 490 nm are achieved. Ti∶sapphire is the main obtain crystal for ultrafast lasers.
