Laser crystals can convert the energy supplied from the outside into highly parallel and monochromic laser crystals with spatial and temporal coherence through optical resonators.   It is the working substance of a crystal laser.   The laser crystal consists of two parts: the luminescence center and the matrix crystal.   The luminescence center of most laser crystals is composed of activated ions which replace the cations in matrix crystals to form doped laser crystals.   When activated ions become part of the matrix crystal components, they form a self-activated laser crystal.ATT offer Various laser crystals.
