LITTLE KNOWN FACTS ABOUT LASER CRYSTAL.

Seen good-point out lasers based on laser crystals are compact and lightweight. Lasers from deep purple to blue are already documented. Primarily, there were a lot of stories on Pr3+ doped laser crystals, and constant wave lasers around 490 nm are accomplished. Ti∶sapphire is the most crucial gain crystal for ultrafast lasers. Superintense ultraf
