Abstract

Polarization stimulated photon echo technique is applied to measure the difference between relaxation rates of alignment and orientation of the level ³P₁ (6s6p) of ¹⁷⁴Yb. At the transition ¹S₀ (6s²) - ³P₁ (6s6p) ¹⁷⁴Yb (of type 0 ↔ 1) a collision induced echo is revealed, which is generated by two pulses of linear and mutually orthogonal polarizations. Photon echo arises exclusively due to collisions between atoms of ytterbium and buffer gases; its power depends non-monotonously on the buffer pressure, and the echo polarizations coincides with the polarization of the first exciting pulse of radiation.
