✦ Synopsis
Shape correlation and magnetic field control of
stimulated photon echo (SPE) are investigated as basic properties
useful for optical data storage and treatment. The SPE
polarization was investigated in ytterbium vapour at the
intercombination transition (6s6p) ^3^P~1~
→ (6s^2^) ^1^S~0~ for the first time in a wide
range of longitudinal magnetic field strength. SPE was generated
by three resonant laser pulses of identical linear polarization
and wave vectors directed symmetrically at small angles to the
axis of cylindric vapour cell. SPE polarization is close to linear
one in zero magnetic field. As magnetic field increases, the SPE
polarization acquires ellipticity with the ellipse axis rotated
around magnetic field vector. Components of SPE polarization show
oscillations versus magnetic field with higher contrast of the
oscillations in the weak field.
