โœฆ Synopsis

Collision induced photon echo generated at the inter-combination transition (6s6p) ^3^P~1~ โ†” (6s^2^) ^1^S~0~ of ^174^Yb in the mixture Yb+Xe is investigated. Collision echo is generated by two unidirectional pulses of resonant radiation with linear and mutually orthogonal polarizations. The collision induced echo appears exclusively due to Yb collisions with buffer, and its polarization coincides with polarization of the first exciting pulse. Experimental results are in qualitative agreement with theoretical predictions for anisotropic depolarizing collisions.

Detailed experimental analysis of photon echo polarization in a longitudinal magnetic field is performed for the first time at the simplest quantum transition __J__ = 1 โ†” __J__ = 0 for which the non-Faraday rotation of photon echo polarization plane was predicted. The echo was generated at the inter
