Continuous-wave self-pumped optical phase conjugation in atomic sodium vapor
Celestino J. Gaeta, Jenny Lam, Richard C. Lind
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.
