Strong nonlinear regime of resonant four-wave mixing in a gas

S. A. Babin, E. V. Podivilov, D. A. Shapiro

The explicit solution is obtained for Raman four-wave mixing ${\omega }_4={\omega }_1-{\omega }_2+{\omega }_3$ of two strong fields $E_1,E_3$ and two weak fields $E_2,E_4$ in a four-level system with the large…
