Effect of magnetic field on the stimulated photon echo in ytterbium vapors

Relaxation characteristics of (6s6p) 3P1 174Yb level

“…This experimental set-up with slight modification was used in our works on non-Faraday rotation of PE [6] and SPE polarization [5], on the PE and SPE application in optical memory [7], and in the search for photon echo induced by anisotropic collisions [3].…”

Polarization of the stimulated photon echo in ytterbium vapour at the transition 0 ↔ 1

“…The dye laser (shown schematically inside the thin line rectangle in figure 1) consisted of a master oscillator (shown schematically by the broken line rectangle) and three amplification stages. The design of the master oscillator is equivalent to those used in our previous work [3][4][5]. The master oscillator permitted rough laser frequency tuning by rotation of grating G (inside the broken line rectangle) and by inclination of the 6 mm base Fabry-Perot interferometer FP (inside the broken line rectangle).…”

“…The fine frequency tuning was performed by variation of the pressure of dry nitrogen filling the chamber with the grating and Fabry-Perot interferometer (see [3] for details). Super-fluorescence of the amplifying dye cells was rejected by spatial filtering of the laser beam as in [3][4][5]. The output laser radiation had linear polarization.…”

The polarization approach to registration femtosecond time slots based stimulated photon echo on the exciton states

“…This led to the emergence surface nanoscale crystal defects. Open (deformation) of the crystal structure of the fibers at the border of contact with the X-ray amorphous phasecreates conditions for the localization of excitons on these surface defects and creates conditions of inhomogeneous broadening of the excitonic spectral lines.In theory, this effect is predicted for the gas atmospheres in the work [3] The first experiment on non-Faraday rotation of the plane polarization of the stimulated photon echo made by the authors of [4] Details polarization dependence of this effect is studied in [5] For the first time this effect on exciton gas detected experimentally in [1,2]. The proposed polarization approach to the registration ultrashort time intervals of at least an order of magnitude superior to existing methods based on the spectrum approach, using devices…”
