Based on the result, of ref. [5], the impulse response of a resonant phase conjugator is calculated with the fourwave mixing. An analytical expression is obtained. This result is compared with that of a Kerr-like phase conjugator, given by R. A. Fisher et al [4]. The difference is discussed.

Self-pumped optical phase conjugation has been demonstrated for the first time to our knowledge in a resonant atomic system. This process was implemented by using a single cw pump beam to excite a sodium-vapor oscillator. The counterpropagating optical fields inside this oscillator then combine with the pump beam in an internal fourwave-mixing interaction to yield the phase conjugate of the incident (pump) beam.
