HELPING THE OTHERS REALIZE THE ADVANTAGES OF LASER CRYSTAL

Seen reliable-state lasers depending on laser crystals are compact and light. Lasers from deep purple to blue are documented. Especially, there have been many reviews on Pr3+ doped laser crystals, and ongoing wave lasers close to 490 nm have been accomplished. Ti∶sapphire is the primary attain crystal for ultrafast lasers. Superintense ultrafast
