Description

Nanostructure-array targets are very attractive for enhancing x-ray intensity generated from femtosecond-laser-produced-plasma. A 40-fold soft x-ray fluence enhancement and a 9-fold pulse peak intensity enhancement is obtained from the 500-nm interval nanohole-array target when it's nanohole diameter is 450 nm. The relatively short x-ray pulse duration of 19 ps can be kept due to the target structure having high local density and nanometer-sized spaces
