Paper Abstract
In this paper, we present our recent progress in the development of rare-earth (Yb3+ or Ho3+) doped Lu2O3 and Y2O3 sesquioxides for high power solid state lasers. We have fabricated high quality transparent ceramics using nano-powders synthesized by a co-precipitation method. This was accomplished by developments in high purity powder synthesis and
low temperature scalable sintering technology developed at NRL. The optical, spectral and morphological properties as
well as the lasing performance from our highly transparent ceramics are presented. In the second part of the paper, we
discuss our recent research effort in developing cladded-single crystal fibers for high power single frequency fiber lasers
has the potential to significantly exceed the capabilities of existing silica fiber based lasers. Single crystal fiber cores
with diameters as small as 35μm have been drawn using high purity rare earth doped ceramic or single crystal feed rods
by the Laser Heated Pedestal Growth (LHPG) process. Our recent results on the development of suitable claddings on
the crystal fiber core are discussed.
