Optical scattering centers in polycrystalline Nd:YAG laser

摘要

For the present study, 1.1-at./100-Nd-doped YAG ceramics with controlled amounts of grain-boundary phase were fab- ricated by a solid-state reaction method using high-purity powders. The optical scattering loss of the Nd:YAG ceram- icws, obtained from Fresnel's equation, increased simply with increased amounts of grain-boundary phase.
