HELPING THE OTHERS REALIZE THE ADVANTAGES OF LASER CRYSTAL

Seen reliable-point out lasers based on laser crystals are compact and light. Lasers from deep purple to blue are actually claimed. Specially, there were a lot of studies on Pr3+ doped laser crystals, and constant wave lasers around 490 nm have already been realized. Ti∶sapphire is the main gain crystal for ultrafast lasers. Superintense ultrafas
