Department of Physics and JILA, University of Colorado at Boulder and NIST, Boulder, Colorado 80309, USA
Phys Rev Lett 99:053902. 2007..We develop an analytical model that describes this grating-assisted x-ray phase matching and predicts that very modest intensities (<10(10) W/cm2) of quasi-cw counterpropagating fields are required for implementation...
