HELPING THE OTHERS REALIZE THE ADVANTAGES OF LASER CRYSTAL

Visible good-condition lasers determined by laser crystals are compact and light-weight. Lasers from deep crimson to blue are already noted. Especially, there have been lots of experiences on Pr3+ doped laser crystals, and constant wave lasers about 490 nm are actually attained. Ti∶sapphire is the main achieve crystal for ultrafast lasers. Superi
