Effect of incoherent beam on photorefractive two-wave mixing in Ce∶KNSBN crystal;

From BaTiO_3:Ce self-pumped phase conjugator, it is theoretically analysised and experimentally demonstrated that non-negative effect of incoherent beam on the four waive mixing region in photorefractive phase conjugator.

This result is experimentally achieved by using incoherent beam illumination along the c axis  direction of the crystal when a He Ne laser generates steady phase conjugate signal.

Detecting the Population relaxation of Organic dye LC700 with the time—delayed degenerate four—wave mixing with incoherent light;

The research for the three-photon correlated imaging with incoherent light(classical thermal light) of lensless Fourier-transform is reported.

Based on the theories of non-diffracting imaging system in coherent light,the measurement system of point spread function(PSF) of non-diffracting imaging system has been presented.

An analytical approach is adopted for the calculation of squeezed property of coherent light interacting with a nonlinear medium of inversion symmetry.

The constructive and destruetive interferences of two bunches of coherent lights arecompletely distinguished by the phase difference:when the phase difference in a multiple of evennumber of π,it is the constructive interference;when it is a multiple of cardinal number of π,it is thedestruective interference.
