FIG. 1.

(Color online) Experimental setup. Seven Raman sidebands are generated in a cell. They are dispersed, passed through a spatial light modulator, recombined, recollimated, and focused into a target chamber. The resultant sideband spectrum generated through four-wave Raman mixing is measured by an array of photodiodes.

(Color online) Maximizing and minimizing the ratio of sideband energies. Each subfigure depicts the energies of seven sidebands after an optimization, with the two wavelengths being optimized shown in solid. In part (a), the energy ratio of the sideband to the sideband is maximized to 3.6. Part (b) shows minimization of the same ratio to 0.68. In part (c), the energy ratio of the sideband to the sideband is maximized to 48. Part (d) shows minimization of the same ratio to 0.67.

(Color online) Convergence of the GA during an optimization of the ratio of energy to energy. Each point represents the average energy ratio over the ten different pulse shapes of one generation of the GA. Values for the minimization of the energy ratio are depicted by circles connected by a solid line and values for maximization of the ratio are depicted by squares connected by a dotted line.

(Color online) Control of sideband energy. The maximum (triangle) and minimum (circle) energies that can be generated for each sideband are depicted. The sidebands are labelled consecutively from to 7 with the initial pump beams being and 0 .
