THE BASIC PRINCIPLES OF LASER CRYSTAL

Visible solid-point out lasers dependant on laser crystals are compact and lightweight. Lasers from deep crimson to blue have already been noted. Especially, there were lots of experiences on Pr3+ doped laser crystals, and continual wave lasers close to 490 nm have been realized. Ti∶sapphire is the key attain crystal for ultrafast lasers.
