LASER CRYSTAL CAN BE FUN FOR ANYONE

Seen sound-state lasers based on laser crystals are compact and lightweight. Lasers from deep purple to blue are documented. Specifically, there have been a great deal of reviews on Pr3+ doped laser crystals, and continual wave lasers all around 490 nm are obtained. Ti∶sapphire is the principle obtain crystal for ultrafast lasers. Superintense ul
