The interaction between coherent light and potassium atoms can produce many nonlinear phenomena as four and six wave mixing, stimulated hyper-Raman scattering, Autler-Townes splitting and electromagnetically induced transparency. These processes are studied in experiment with fs laser light of high intensity, with two-photon excitation of the 6S state of potassium atom, and theoretically solving numerically the density matrix equations in a simlified four level potassium atom model. In a pump-probe configuration the use of a second weak laser field can modiify the polarisation of the system and can enhance the four wave mixing emissions of the desired de-excitation path. The role of the weak probe field in a V or Λ scheme is studied. The...
