HELPING THE OTHERS REALIZE THE ADVANTAGES OF LASER CRYSTAL

Obvious sound-state lasers dependant on laser crystals are compact and lightweight. Lasers from deep pink to blue happen to be noted. Particularly, there have been many studies on Pr3+ doped laser crystals, and steady wave lasers about 490 nm are attained. Ti∶sapphire is the main achieve crystal for ultrafast lasers. Superintense ultrafast lasers
