THE SMART TRICK OF LASER CRYSTAL THAT NO ONE IS DISCUSSING

Obvious good-condition lasers dependant on laser crystals are compact and lightweight. Lasers from deep pink to blue have been claimed. Specially, there were lots of experiences on Pr3+ doped laser crystals, and constant wave lasers about 490 nm are already accomplished. Ti∶sapphire is the most crucial achieve crystal for ultrafast lasers. Superi
