Double phase conjugation in media with a local response

Igor' M Bel'dyugin, M V Mel'kumov, K. A. Sviridov

An analysis is made of double phase conjugation in media with a local response. A threshold is found for the generation of a phase-conjugated wave by the double process in a medium with a local response and with additional amplification. An analysis is made of the further possibilities of generation of phase-conjugated radiation in the case of a four-wave interaction characterized by a feedback loop established when double phase conjugation takes place in a nonlinear medium. The threshold intensity of the input radiation ensures possible generation of a phase-conjugated wave as a result of a four-wave interaction characterized by a feedback loop and merging of counterpropagating beams in a nonlinear medium.

Generation in the double-conjugation scheme for a medium with a local transient response

A. V. Mamaev, Vladimir V. Shkunov

It is shown that the minimum threshold in the double-conjugation scheme for a medium with a local transient response takes place for the generated waves with angular tilting.

Experimental and theoretical double-pumped phase conjugation in inverted Nd:YAG

Darren Udaiyan, R.P.M. Green, D.H. Kim +2 more

Summary form only given. Double-pumped phase conjugation (DPPC) has been studied in photorefractives and in media with local response. A laser amplifier is an example of a medium with local response, by the formation of gain gratings (via spatial hole burning) from two coherent beams. In this work we demonstrate experimentally DPPC in a gain medium (Nd:YAG) and show that it can produce high powers, high reflectivities, and fast response times compared to DPPC in photorefractives.
