Polarization properties of the modified stimulated photon echo in ytterbium vapor
Evseev I. V., Ermachenko V. M., Reshetov V. A.
Keller and Le Gouet's experiment on the modified stimulated photon echo in ytterbium vapor is explained. The photon-echo method has been used for the first time to obtain information on the alignment relaxation time. There is a way to alter the experimental conditions in order to determine the orientation relaxation time.
