HELPING THE OTHERS REALIZE THE ADVANTAGES OF LASER CRYSTAL

Visible solid-point out lasers depending on laser crystals are compact and light-weight. Lasers from deep pink to blue are already described. Specially, there have been plenty of reports on Pr3+ doped laser crystals, and constant wave lasers all over 490 nm happen to be obtained. Ti∶sapphire is the primary achieve crystal for ultrafast lasers. Su
