CONSIDERATIONS TO KNOW ABOUT LASER CRYSTAL

Seen solid-state lasers based upon laser crystals are compact and lightweight. Lasers from deep red to blue are already described. Especially, there have been lots of reviews on Pr3+ doped laser crystals, and steady wave lasers close to 490 nm are attained. Ti∶sapphire is the key acquire crystal for ultrafast lasers. Superintense ultrafast lasers
