The code GEFIE-QUAD (gratings electric field integral equation on quadrilateral grids) is a first-principles simulation method to model the interaction of laser light with diffraction gratings, and to determine how grating imperfections can affect the performance of the compressor in a CPA laser system. GEFIE-QUAD gives scientists a powerful simulation tool to predict the performance of a realistic laser compressor.
Our research explores a number of different scientific simulation fields, most of which have particular significance to LLNL programs (e.g., high-energy-density physics). Other scientific simulation work showcases the Lab’s high performance computing capabilities in collaborative efforts with scientists at other institutions.
