THE FACT ABOUT LASER CRYSTAL THAT NO ONE IS SUGGESTING

Seen solid-state lasers based on laser crystals are compact and lightweight. Lasers from deep pink to blue are noted. Specially, there have been a lot of studies on Pr3+ doped laser crystals, and continuous wave lasers around 490 nm have already been reached. Ti∶sapphire is the main attain crystal for ultrafast lasers. Superintense ultrafast lase
