LASER CRYSTAL CAN BE FUN FOR ANYONE

Seen strong-point out lasers based on laser crystals are compact and lightweight. Lasers from deep purple to blue are described. Specially, there have been lots of experiences on Pr3+ doped laser crystals, and continual wave lasers close to 490 nm have been achieved. Ti∶sapphire is the leading get crystal for ultrafast lasers. Superintense ultraf
