HELPING THE OTHERS REALIZE THE ADVANTAGES OF LASER CRYSTAL

Obvious strong-condition lasers according to laser crystals are compact and lightweight. Lasers from deep red to blue are actually reported. Especially, there were a great deal of reports on Pr3+ doped laser crystals, and continual wave lasers all around 490 nm happen to be reached. Ti∶sapphire is the leading achieve crystal for ultrafast lasers.
