Abstract The paper considers the implementation of logical operations with sets presented as images in the accumulated photon echo mode. It is shown that the photon echo mode may be used to perform the operation of combining sets.

The effects of level degeneracy on the polarization dependence of photon echoes and of combination tones in gases are compared. A remarkable similarity in behavior is found to exists, with quantitative agreement in the case of several simple transitions. By analogy, the echo behavior for elliptically polarized input pulses is suggested.

The effect of photon echo is studied in several multilevel systems with quasi-equidistant spectra. The analysis focuses on the echo schemes that are of interest for femtosecond photon echo experiments involving both fundamental and combination vibrational modes of molecules.
