Variables affecting the absorption of high-irradiance 10 to the 15th power to 10 to the 16th power Wsq cm laser light in plasmas were studied experimentally and where possible related to theory. It was found that temporally structured laser pulses, simulating those required in many pellet implosion designs, exhibit very enhanced backscatter consistent with Brillouin. The variation of absorption with focal position and incident irradiance, and the critical surface structure inferred from scattered laser light will be described and their implications to laser fusion discussed.
