Abstract

It is shown the dynamic signal energy range within which the reflection coefficient of a phase-conjugation mirror (in a four-wave mixing system with a strong signal wave) remains constant at 40%, can be increased to 5.5 orders of magnitude.

Effective reflectance in millimeter-wave range

V. I. Kislenko, A. D. Lomakin, R. M. Yaroshenko

Spatio-temporal characteristics of phase-conjugate processes on the basis of a stimulated scattering or three-wave mixing are considered. On an instance of phase conjugation for a dipolar spin wave pulse at microwave frequency, conjugate mirror effective reflectance application in case of instantaneous nonlinearity is shown.

Kinetics of the evolution of an absolute instability due to the Brillouin nonlinearity under four-wave mixing conditions

I Yu Anikeev, Dmytro Glazkov, Iosif G. Zubarev +1 more

A four-wave hypersonic phase-conjugate mirror was proposed and implemented to observe the evolution of an absolute instability under conditions of continuous variation of the wave mismatch δ k . Kinetic equations describing four-wave mixing under conditions of an absolute instability of counterpropagating reference waves are solved numerically taking into account the group delay effect. Strong modulation of all the waves at the exit from a medium of length L is predicted theoretically and observed experimentally when δ kL = 0. This disappears with increasing wave mismatch δ kL ≈ 2π. Estimates are obtained of the maximum theoretical sensitivity and the maximum reflection coefficient of the signal wave incident on such four-wave hypersonic phase-conjugate mirrors.

Gain and phase-conjugation fidelity of a four-wave Brillouin mirror based on methane

Rolf W. F. Gross, Sherwin T. Amimoto, Lissa Garman-DuVall

We report measurements of the gain and phase-conjugation fidelity of a nondegenerate four-wave Brillouin mirror (FWBM) based on high-pressure methane. In the experiments we used a Nd:YAG laser that produced single-mode pulses of 13-nsec duration. Depending on the energy of the pump we measured signal reflectivities between 10 and 10(3), constant over six orders of magnitude of signal energy. We also determined the conjugation fidelity of the FWBM by measuring the Strehl ratio of the conjugated return as a function of the energy of the input signal. We show that the Strehl ratio reduces to 0.5 for an input energy of 1.5 x 10(-13) J/mode of the FWBM. This noise-equivalent signal energy constitutes the limiting sensitivity of the FWBM. Our experiments show that a gas-filled FWBM could be used as a phase conjugator and high-repetition-rate optical image intensifier.
