1. What’s phase conjugation First proposed by Va. Zel'dovich and his colleagues in Moscow

1. What’s phase conjugation First proposed by Va. Zel'dovich and his colleagues in Moscow in 1972, with stimulated Brillouin scattering effect. Firstly, main applications in free space (spatial): The forward and the backward light have the same wavefront.

2. Applications of phase conjugation 1. Adaptive Optics; 2. Lensless Imaging; 3. Generating "Time-reversed"

2. Applications of phase conjugation 1. Adaptive Optics; 2. Lensless Imaging; 3. Generating "Time-reversed" Light; 4. Phase-Conjugate Resonators; 5. Image processing; 6. Associative memory; 7. Frequency effect/ shift; 8. Time-Domain Applications (dispersion and nonlinear effect compensation).
