Here we show that 1?100?J pump pulses can amplify picojoule seed pulses to nearly joule level. The extremely high gain also leads to significant amplification of backscattered radiation from ?noise?, arising from stochastic plasma fluctuations that competes with externally injected seed pulses, which are amplified to similar levels at the highest pump energies. The pump energy is scattered into the seed at an oblique angle with 14?J?sr?1, and net gains of more than eight orders of magnitude. The maximum gain coefficient, of 180?cm?1, exceeds high-power solid-state amplifying media by orders of magnitude. The observation of a minimum of 640?J?sr?1 directly backscattered from noise, corresponding to ?10% of the pump energy in the observation solid angle, implies potential overall efficiencies greater than 10%.
