HIGH HARMONICS GENERATION OF LIGHT

摘要

A method of generating light is disclosed. The method comprises irradiating a substance (12) with first optical field (16) of a first frequency and second optical field (20) of a second frequency. The second frequency being higher than a cutoff frequency of a harmonics generation HGS spectrum characterizing the interaction of the substance (12) with the first optical field (16). Furthermore, an apparatus (10) comprises the substance (12), a first light source (14) for generating the first optical field (16) and a second light source (18)- for generating the second optical field (20).
