Observation and modeling of dynamic instabilities in the mutually pumped bird-wing phase conjugator in BaTiO_3

Abstract

We observed dynamic instabilities in the phase-conjugate outputs from the mutually pumped bird-wing phase conjugator in BaTiO3. We present experimental results that illustrate typical output characteristics and compare these with the results of a computer model that self-consistently determines all the relevant beam intensities within the crystal. The role of mutual erasure and the assisted routes to total-internal-reflection self-pumping are included within the model and are discussed in the context of the experimental results.
