Popis:	Polarization properties of photon echo generated at the inter-combination transition (6s2) 1S0 ↔ (6s6p) 3P1 of 174Yb (transition of type 0 ↔ 1) are for the first time investigated experimentally for a complete set of polarizations of two exciting pulses of resonant radiation (linear-linear, circular-linear, linear-circular, and circular-circular) in a pure ytterbium vapor. In all cases the photon echo polarization coincides with polarization of the second exciting pulse. Photon echo in a pure gas does not appear neither for exciting pulses of mutually orthogonal linear polarizations, nor for the pulses of opposite circular polarizations. Experimental results are in agreement with theoretical predictions.
