We have analyzed the Hanle effect on the closed ${F}_{\mathrm{g}}=\stackrel{\ensuremath{\rightarrow}}{3}{F}_{\mathrm{e}}=4$ ${D}_{2}$ -line transition of ${}^{85}\mathrm{Rb}.$ Exciting the rubidium atoms by circularly polarized laser light, and scanning an applied transverse magnetic field, a bright resonance Hanle signal is obtained at different values of an applied longitudinal magnetic field. We report experimental and numerical evidence of this bright resonance.We have analyzed the Hanle effect on the closed ${F}_{\mathrm{g}}=\stackrel{\ensuremath{\rightarrow}}{3}{F}_{\mathrm{e}}=4$ ${D}_{2}$-line transition of ${}^{85}\mathrm{Rb}.$ Exciting the rubidium atoms by circularly polarized laser light, and scanning an applied transverse magnetic field, a bright resonance Hanle signal is obtained at different values of an applied longitudinal magnetic field.

Polarization rotation of photon echo at J = 0 ↔ 1 transition in magnetic field

В. Н. Ищенко, Sergei A. Kochubei, Хворостов Евгений Борисович +2 more

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 ↔ J = 0 for which the non-Faraday rotation of photon echo polarization plane was predicted. The echo was generated at the intercombination transition (6s6p) 3P1 → (6s2) 1S0 of 174Yb by two resonant laser pulses of linear (parallel or mutually orthogonal) polarization, and the angled echo optical scheme was applied for the detection. At the magnetic field strength ℬ ⩽ 5 G the photon echo has polarization very close to linear one; its polarization plane rotates around magnetic field vector, and photon echo polarization components and integral echo power oscillate versus ℬ from its maximum value to zero, in agreement with theory. At a stronger magnetic field ℬ ∼ 40 G photon echo power oscillations disappear, no preferable orientation of polarization vector is observed; the fluctuations of exciting radiation spectrum are supposed to be responsible for this "non-polarized" echo.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 ↔ J = 0 for which the non-Faraday rotation of photon echo polarization plane was predicted.
