The unusual experimental result of spectral narrowing of reflected laser pulses was attributed to deceleration of the critical (reflective) electron density surface due to the radiation pressure. A mechanism different from the Doppler effect that can cause spectral shifts was identified; a plasma reflectivity that changes rapidly in time can act as a frequency filter when the reflected laser pulse is chirped. The plasma expansion length and temperature that were calculated with the model was used to estimate the X-ray emission from the plasma with a simple scheme involving Kirchhoffs radiation law and Planck's black body radiation law.81 p.application/pdfengCopyright is held by the author, unless otherwise indicated.
