title: Highly efficient degenerate four-wave mixing with multipass geometries in a polymer laser dye saturable amplifier.
abstract: We demonstrate the use of highly efficient degenerate four-wave mixing for phase conjugation with multipass geometries in a polymer laser dye saturable amplifier. Phase-conjugate energy reflectivity of as much as 20,000% with a four-pass geometry in the longitudinally pumped polymer dye was obtained at 564 nm.
