EFFICIENT HARONIC GENERATION OF BROAD AND HIGH POWER LASER AND ITS NEW DEVELOPMENTS

We have reviewed the theoretical model on harmonic generation of broad-band high power lasers and its methods for efficient frequency conversion, in this paper. Based on the discussion and analysis for the features and shortcomings of angular spectral dispersion and crystal quadrature, both improvements and future applications have been presented,furthermore,we have proposed and studied frequency conversion with LBO crystal suitable for small-aperture multi-beam high power laser systems.
