A Novel Composite Ceramic Laser Material Embedded With Single Crystal Rare-Earth Compound Nanorods
Rare-Earth (RE) related laser materials typically suffer from several key drawbacks. Materials are made by doping ceramic powders with rare earth elements, but this approach has many associated drawbacks. Low doping density limits the optical gain to a relatively low level, while doping levels which are too high cause nonhomogeneous dopant distributions....
