Abstract
A system for frequency conversion, comprises a laser source and a harmonic generation crystal. The laser source is configured to produce optical pulse energy of less than 100 μJ. The harmonic generation crystal comprises a structure characterized by a nonlinear susceptibility, and a crystal grating period which adiabatically varies along the longitudinal direction in a manner that the crystal grating period is inversely proportional to a crystal grating function of a coordinate z measured along the longitudinal direction.
