| Abstract: | Transient two-wave coupling gain versus delay time between the pump beam and the probe beam in GaAs has been measured, and the properties of various processes in two-wave coupling are analyzed. A change in the polarization of coupling beam is predicted and has been observed. It has been shown that ps two-wave coupling is a new way to realize ps optical switching. |
