LITTLE KNOWN FACTS ABOUT LASER CRYSTAL.

Noticeable strong-state lasers according to laser crystals are compact and lightweight. Lasers from deep purple to blue are documented. Particularly, there have been plenty of stories on Pr3+ doped laser crystals, and steady wave lasers all-around 490 nm are accomplished. Ti∶sapphire is the most crucial obtain crystal for ultrafast lasers. Superi
