title: Absorption of subpicosecond UV laser pulses during interaction with solid targets.
abstract: The absorption of subpicosecond uv laser pulses has been measured at intensities above 10(17) W/cm(2). High levels of absorption were observed, up to 55% for s polarization and 65% for p polarization. The behavior with angle of incidence and polarization can be interpreted as due to a combination of resonance and collisional absorption, taking place in a plasma with a scale length of the order of a fraction of the laser wavelength.
