Two-wavelength reconstruction in doublet degenerate four-wave mixing
The demonstration of two-wavelength backward reconstructed waves is reported for the first time in this paper. In doublet degenerate four-wave mixing, using lasre pulses from SH of the Q-switched Nd:YAG laser system as a writing-beam and an object- beam, and a continuous Ar+-laser as a readout-beam, a reconstructed wave at 532.0 nm is obtained besides a reconstructed wave at 514.5 nm which was observed in common doublet degenerate four-wave mixing. These reconstructed waves with different wavelengths propagate along different directions and the time oharacterd of them are different. These results are in agreement witih theoretical analysis.
