Nonlinear properties of Fabry-Perot interferometer in the conditions of inhomogeneous broadening of electron paramagnetic resonance (EPR) line

Alexey A. Vertiy

Investigation of behaviour of a nonlinear Fabry-Perot interferometer with a paramagnetic filling in the conditions of inhomogeneous broadening of the electron paramagnetic resonance line is of interest for different implementations in the spectroscopy, quasioptics and dynamic nuclear polarisation.

Nonlinear spectra of a homogeneously and inhomogeneously broadened two-level system

Amenaida Ferrer Marcano, O. M. C. Salazar, J. L. Paz +2 more

Polarization and Rayleigh type optical mixing spectra of a homogeneously and inhomogeneously broadened two-level system are calculated. We show that the nonlinear signal has contributions from the population pulsation and saturation effect. In the homogeneous system these effects can induce an asymmetric spectrum when the probe frequency is different from the resonant value. In the inhomogeneous system the spectral response is always symmetric independent of the probe frequency value. Line saturation and dynamic stark splitting are substantially reduced in the inhomogeneous case. The mentioned differences can be used to identify the type of broadening of a given spectral line.

Spin frequency comb echo memory controlled by a pulsed-gradient of magnetic field

K. I. Gerasimov, S. A. Moiseev, V. I. Morozov +1 more

The controllable storage and on demand retrieval of the microwave pulses by using the photon echo quantum memory approach based on a spin frequency comb of inhomogeneous broadening (SFC- protocol) have been demonstrated. We have used an electron-nuclear spin ensemble of tetracyanoethylene anion radicals in toluene which has a natural periodic structure of narrow electron-spin resonance (ESR) hyperfine lines. On-demand retrieval of the stored field has been realized by using two pulses of the magnetic field gradient of an opposite polarity which hold the electron spins in a dephased excited state during the storage time. The obtained experimental results demonstrate promising properties for coherent controlling the electron-nuclear spin ensemble of radicals in liquid that could be useful for implementation of room-temperature broadband quantum memory.
