HELPING THE OTHERS REALIZE THE ADVANTAGES OF LASER CRYSTAL

Obvious stable-point out lasers according to laser crystals are compact and lightweight. Lasers from deep purple to blue are described. Specially, there were many studies on Pr3+ doped laser crystals, and continuous wave lasers all over 490 nm happen to be obtained. Ti∶sapphire is the key attain crystal for ultrafast lasers. Superintense ultrafas
