Research output: Contribution to journalConference articlepeer-review


Plasmas have recently received considerable attention as potentially efficient long wavelength (infrared to microwave) phase con-jugators using degenerate four-wave mixing (DFWM). However, the current theory assumes an idealized isotropic, homogeneous, quiescent plasma. In order to ascertain the suitability of plasmas for phase conjugation applications, a more complete theory of DFWM in the presence of plasma density inhomogeneities, turbulence, etc. is necessary. This paper focuses on the effect of density inhomogeneities on the DFWM and phase conjugate properties of plasmas. In addition, a comparison is made between DFWM in collisionless and collisional plasmas.
