Blue-Green Laser.
Abstract
The patent application concerns a blue-green solid state laser which operates at room temperature and uses as its active medium an LiYf4 crystal as the host material for the trivalent rare earth ion Tb(3+). High Tb concentrations, 20% or more, are employed for the purpose of increasing the absorption co-efficient and for obtaining an efficient transfer process. At the lower end of this scale, Gd may be included to further increase the pumping efficiency by the energy transfer from Gd to Tb. Blue-green lasers have potential application to underwater communications and viewing systems.
