Abstract
The possibility is considered of formation of a multifrequency-radiation wave front (with a wide line spectrum in the interval ω, ω+Δω), reversed with respect to the wave front of a signal wave of frequency ω0 unequal to the frequencies in the indicated spectrum. The wave front reversal (phase conjugation) is achieved by diffraction of a multifrequency light wave in a direction counter to that of the signal, on a three-dimensional dynamic hologram produced by electromagnetic fields of frequency ω0 in a resonant medium (with thermal nonlinearity) that is fully transparent to the multifrequency radiation. A single direction of the radiation diffraction at all frequencies of the spectrum is ensured by preliminary passage of the initial multifrequency wave through a simple dispersive prism that deflects the direction in each spectral line in proportion to the frequency change. The basic equations describing a similar phase conjugation method are derived, and the efficiency of the conjugation are estimated using as an example multifrequency emission of a chemical cw HF laser.
