Abstract
Ultra-broadband multifrequency Raman generation (UMRG) is one of the most novel nonlinear optical processes to have emerged over the last few years. With H2 gas as the Raman medium, we predicted that nearly 50 distinct frequencies of comparable energy may be generated.1,4 For UMRG in air, beams containing around 150 waves may be attained.5 Experimental results that support our overall predictions are appearing in the literature. However, some configurations exhibit competition between distinct Raman resonances. This feature may have serious consequences for many of the proposed applications for UMRG. Here, we present new analyses and simulations that take such nonlinear competing processes into account.
