摘要

The physics of fast ignition is being studied using a petawatt laser facility at the LawrencernLivermore National Laboratory. Performance of the PW laser with deformable mirror wavefrontrncontrol giving intensities up to 3×10~(20) Wcm~(-2) is described. Measurements of the efficiency ofrnconversion of laser energy to relativistic electrons and of their energy spectrum and angularrndistribution including an observed narrow beam angle of ±15o, are reported. Heating by the electronsrnto near 1keV in solid density CD_2 is inferred from the thermo-nuclear neutron yield. Estimatesrnsuggest an optimized gain of 300x if the National Ignition Facility were to be adapted for fastrnignition.
