THE SINGLE BEST STRATEGY TO USE FOR LASER CRYSTAL

Obvious reliable-state lasers based upon laser crystals are compact and lightweight. Lasers from deep crimson to blue are described. Specially, there have been lots of studies on Pr3+ doped laser crystals, and constant wave lasers all around 490 nm are already accomplished. Ti∶sapphire is the key acquire crystal for ultrafast lasers. Superintense
