Experiments were performed on the Janus laser with ..cap alpha..- spherical illumination system producing very nearly uniform energy deposition on microscopic laser fusion targets. The target performance as measured by the thermonuclear reaction yield was increased by a factor of 2.5 over experiments performed with f/1 lenses. Simple considerations of useful absorbed energy together with ..cap alpha..-particle time-of-flight measurements indicate that the D-T ion temperatures were not increased over those of earlier experiments. The increased neutron yield is thus to first order caused by the greater uniformity of compression achieved. Measurements of absorption as a function of focal overlap of the ellipsoidal mirrors support the hypothesis that resonance absorption plays an important role in these laser fusion experiments.
