FACTS ABOUT LASER CRYSTAL REVEALED

Noticeable sound-condition lasers based on laser crystals are compact and light. Lasers from deep red to blue are already documented. Especially, there were a lot of reports on Pr3+ doped laser crystals, and steady wave lasers close to 490 nm have already been reached. Ti∶sapphire is the key gain crystal for ultrafast lasers. Superintense ultrafa
