LITTLE KNOWN FACTS ABOUT LASER CRYSTAL.

Seen sound-point out lasers based upon laser crystals are compact and light. Lasers from deep purple to blue are already claimed. Specially, there have been lots of reports on Pr3+ doped laser crystals, and continual wave lasers close to 490 nm are actually reached. Ti∶sapphire is the most crucial acquire crystal for ultrafast lasers. Superintens
