NOT KNOWN DETAILS 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. Especially, there were loads of reports on Pr3+ doped laser crystals, and continuous wave lasers all over 490 nm are already achieved. Ti∶sapphire is the primary achieve crystal for ultrafast lasers.
