Abstract

We report on experimental plasma absorption of 0.35 μm radiation incident on plane targets. Absorption fractions between 50 and 98% were found for UV pulses of 90 and 450 ps duration on planar CH, nickel, and gold targets for intensities between 10¹³ and 3 × 10¹⁵ W/cm². The results are in agreement with computer calculations using inverse bremsstrahlung absorption and a thermal electron heat flux limiter between 0.03 and 0.06.
