GADOLINIUM-GALLIUM-GARNET LASER DOPED WITH CR

摘要

A broadly wavelength-turnable laser is provided which comprises as the laser medium a single crystal of GGG:Cr3+. The laser may be operated over a broad temperature range from cryogenic temperatures to elevated temperatures. Emission is in a spectral range from red to infrared, and the laser is useful in the fields of defence, communications, isotope separation, photochemistry, etc.
