Ever heard of the water window? It consists of radiations in the 3.3 to 4.4 nanometer range, which are not absorbed by the water in biological tissues. A new theoretical study identifies the physical mechanism needed to efficiently generate harmonic radiations at high laser intensities that occur beyond the saturation threshold of atoms and molecules. These findings are aimed at improving conventional methods of coherent radiation production to reach the water window.
