Abstract: It has been understood on the whole that status of laser leaked from X-ray conversion region to the implosion field by more than three years experimental investigation in thispaper,the total energy and angular distribution of leakage laser have been measured by using the modified scattered light detector, and the S/N has been raised greatly.The temporal features ofleakage laser have been measured by using C979 optical streak camera.Therefore. we have got higher precision measuring re- sults of the energy and temporal waveform of leakage laser, and these results provides di- rect basis for understanding the physical mechanism of implosion fusion.
