| 1. | In photorefractive crystal light illumination changes the refractive index of the crystal due to linear electrooptical effect , which in turn changes the light distribution . as a result of the development of this process , a beam , called the phase conjugation wave , leaves the crystal back along the direction of the incident beam and is its phase conjugate replica
光折变晶体在光辐照下，通过晶体中的线性电光效应而产生折射率随光强的空间分布而变化，即在晶体内建立起体相位栅。 |
