Efficient coupling of 527 nm laser beam power to a long scalelength plasma

摘要

We experimentally demonstrate that application of laser smoothing schemes including smoothing by spectral dispersion (SSD) and polarization smoothing (PS) increases the intensity range for efficient coupling of frequency doubled (527 nm) laser light to a long scalelength plasma with n(e)/n(cr) = 0.14 and T-e = 2 keV.
