LASER CRYSTAL CAN BE FUN FOR ANYONE

Visible good-point out lasers based on laser crystals are compact and light. Lasers from deep pink to blue have been reported. Primarily, there were many experiences on Pr3+ doped laser crystals, and ongoing wave lasers all-around 490 nm have been achieved. Ti∶sapphire is the main get crystal for ultrafast lasers. Superintense ultrafast lasers wi
