OPTICAL RETUNING OF SPECTRAL CHARACTERISRICS OF QUANTUM- CASCADE STRUCTURES USING FOR SPECTROSCOPIC DETECTION OF EXPLOSIVES

S. I. Petrov, M.V. Klimenko, Шулика Алексей Владимирович

In this paper we come up with a new approach to retuning the spectral characteristics of quantum-cascade structure amplification. The process of retuning proceeds using the continuous-wave optical pumping and it is strongly dependent upon the phase space filling effect. As suggested by the results from the mathematical simulation of the quantum-cascade structure optical properties, this particular method allows the spectral amplification characteristics to be retuned within the limits of 1.1 meV with no substantial change in the plan gain magnitude. The results thus obtained is of certain interest for spectroscopic detection of explosive.

NON-LAGRANGIAN NONLINEARITY AND COHERENT OPTICAL WAVE MIXING PROCESSES

A.L. MURAZYAN, Nelson V. Tabiryan, B. YA. ZEL’DOVICH +1 more

Interaction of optical beams in media with diagonal-bipolar nonlinearity is theoretically investigated. It is shown that the nonlinearity is not Lagrangian and allows processes violating energy flux conservation law. Conditions for energy exchange to take place are found. Probe beam amplification in the field of counterpropagating pumps and wavefront conjugation are investigated to exhibit some remarkable features. Coherent interaction of waves of different frequencies through recording static gratings is shown to lead also to energy exchange processes owing to non-Lagrangian character of nonlinearity.
