Abstract
We formulate a theory of quasi-phase matching of high harmonic generation using weak counterpropagating pulse trains. We predict the optimal laser intensities and pulse shapes for the counterpropagating field and find that the conversion efficiency is better than the efficiency obtained by simply suppressing harmonic emission from out-of-phase regions.
