The study of mutually pumped phase conjugate in adaptive optical heterodyne

摘要

The photorefractive adaptive optical heterodyne detection system (PAOHDS) is proposed. The dynamic properties of mutually pumped phase conjugate (MPPC), the key technology to the PAOHDS, are studied theoretically. The three-dimensional distribution of MPPC refraction index grating in time and length axis is simulated numerically. The dependence of dynamic properties of MPPC on the intensity of the fanning light is presented.The stronger the intensity of the fanning light is, the less response time for MPPC is. The dependence of dynamic properties of MPPC on the coupling strength is presented. The greater the coupling strength is, the less response time for MPPC is. These results provide theoretical basis to reduce response time of PAOHDS.
