GETTING MY LASER CRYSTAL TO WORK

Obvious good-condition lasers dependant on laser crystals are compact and light-weight. Lasers from deep purple to blue have been described. Especially, there were lots of reviews on Pr3+ doped laser crystals, and steady wave lasers around 490 nm have already been achieved. Ti∶sapphire is the key get crystal for ultrafast lasers. Superintense ult
