Figure 1: Generation of new frequency components via fourwave mixing. In the explanation above, it was assumed that four different frequency components interact via fourwave mixing. This is called nondegenerate fourwave mixing. However, there is also the possibility of degenerate fourwave mixing, where two of the four frequencies coincide.

For a stimulated degenerate four wave mixing process, two degenerate pump photons mix with a signal photon to generate the idler photon. For an efficient frequency generation, the energy and the momentum should be conserved. Energy conservation can be written in terms of the pump l p, the signal l s and the idler l c photon wavelengths as 2 lll ps c=+11. Momentum conservation implies phase

· We experimentally investigate the gain spectrum for a pair of conjugated beams through stimulated degenerate fourwave mixing (DFWM) using Cs vapor. The experimental results showed that the DFWM can only occur when the angular momentum of the ground state is larger than or equal to that of the excited state ( F g ≥ F e ) for the F g → F e transition.

Two common forms of fourwave mixing are dubbed sum frequency generation and difference frequency generation. In sum frequency generation three fields are input and the output is a new high frequency field at the sum of the three input frequencies. In difference frequency generation, the typical output is the sum of two minus the third.
