Nonlinear optical processes strongly depend on the relative phases among interacting light waves, and the flow of optical energy can be controlled through phase manipulation. In high-order Raman-resonant four-wave mixing in para-hydrogen, various optical emission patterns have been realized by controlling the relative phases. In this study, a genetic algorithm was introduced to search for phase conditions that enable more efficient light generation. As a result, an energy concentration into the first anti-Stokes mode (AS1) was achieved with a conversion efficiency of 87%.
