THE SMART TRICK OF LASER CRYSTAL THAT NO ONE IS DISCUSSING

Noticeable sound-state lasers depending on laser crystals are compact and light. Lasers from deep pink to blue have been noted. Especially, there have been lots of experiences on Pr3+ doped laser crystals, and constant wave lasers about 490 nm have been accomplished. Ti∶sapphire is the main achieve crystal for ultrafast lasers. Superintense ultra
