Study on Phase Matching in Parametric Six-Wave Mixing in Rb

Abstract

Parametric six-wave mixing processes have been achieved in Rb and two parametric six-wave mixing channels, 5S→→5D→→6P→→S1/2→→P1/2→→5S and 5S→→5D →→P→→S1/2→→52P3/2→→5S, have been identified. Competition between the two channels is observed and, furthermore, phase matching conditions in the two channels are analyzed and calculated. The calculation results agree well with the experimental observations, indicating that the phase matching is the main factor governing the competition between the two parametric six-wave mixing channels.
