THE BEST SIDE OF LASER CRYSTAL

Obvious stable-condition lasers based upon laser crystals are compact and light-weight. Lasers from deep red to blue happen to be noted. Particularly, there have been a lot of experiences on Pr3+ doped laser crystals, and ongoing wave lasers close to 490 nm have been realized. Ti∶sapphire is the key attain crystal for ultrafast lasers. Superinten
