Abstract
In this paper, we have discussed the enhanced three-wave mixing (TWM) nonlinear optical processing in a three-level symmetry broken three-level quantum system. The quantum system interacts with three drivel laser fields out of which two are weak probes and generated signal beams and one of them is strong coupling light. We have shown that due to symmetry broken of quantum system the nonlinear sum frequency generation leads to TWM. By adjusting the different system parameters, the efficiency of TWM mechanism can be improved. Moreover, we have found when the strong coupling light becomes optical vortex light, the efficiency of TWM depends on the orbital angular momentum (OAM) light. Our proposed model may be having useful applications in nonlinear spectroscopy based on OAM.
