The study on the Fe: LN crystal was developed early and the holographic storage, optical amplification and phase conjugation mirror have been carried out, but at present, many problems on the research of Fe: LN crystal are unresolved, for example, the absorption is strong for A_r^+-ion laser beam, the energy loss of light source is large, the scattering of the output light beam is intense, the spatial distribution is not uniform, etc. Therefore, it is necessary to fur-展开更多
