Picosecond phase-conjugate reflection from organic dye saturable absorbers

Enlace externo

Phase conjugation with conversion efficiences of up to 50% has been obtained in DODCI and other saturable absorbers with picosecond pulses from a mode-locked dye laser. Reflectivity shows a quadratic dependence on pump intensity up to $latex \sim 500 \ MW cm-2$
