HELPING THE OTHERS REALIZE THE ADVANTAGES OF LASER CRYSTAL

Seen reliable-state lasers determined by laser crystals are compact and light-weight. Lasers from deep red to blue have been claimed. Specially, there were loads of stories on Pr3+ doped laser crystals, and steady wave lasers all around 490 nm have been obtained. Ti∶sapphire is the principle gain crystal for ultrafast lasers. Superintense ultrafa
