Sub-lambda gratings, surface plasmons, hotter electrons and brighter x-ray sources- enhanced absorption of intense, ultrashort laser light by tiny surface modulations

Subhendu Kahaly, G. Ravindra Kumar

We observe near 100 % absorption of light in intense ultrashort laser plasma interaction in a metal coated (Au on glass) sub-lambda grating structure under suitable conditions and…
