摘要: The interaction of an ultrashort intense laser pulse with a subwavelength rectangular grating target is studied by analytical model and particle-in-cell simulations. Such excites strong periodic charge separation at the surface. With presence formed electrostatic fields, field can intensively heat electrons, causing near 100% light absorption. Its dependence on parameters given. At low or moderate intensity, there are optimized sizes gibbous cells grooves as well groove depths which absorption maximums found. high weakly affected depths.
