LASER CRYSTAL NO FURTHER A MYSTERY

Seen good-point out lasers depending on laser crystals are compact and light-weight. Lasers from deep red to blue have already been noted. Particularly, there have been plenty of reports on Pr3+ doped laser crystals, and continual wave lasers close to 490 nm happen to be obtained. Ti∶sapphire is the leading achieve crystal for ultrafast lasers. S
