Photon-echo detection by six-wave mixing.
Picosecond photon echoes have been generated and detected by using a resonant six-wave mixing effect. In this process, the induced echo polarization is used to drive a four-wave mixing process. The merits of this method compared with other techniques of photon-echo detection are discussed. Further examples of spectroscopically useful six-wave mixing effects are presented.
