摘要：
Measurements of the 3-omega-0/2 emission from laser-irradiated targets at 0.53-mu-m were made at three angles over a wide range of laser bandwidths with and without induced spatial incoherence (ISI) echelons. The 3-omega-0/2 emission was found to be correlated with hard x rays but not Raman spectra, suggesting that the 3-omega-0/2 radiation was due to two-plasmon decay. Reduction of both 3-omega-0/2 emission and the accompanying hard x rays by ISI required five to ten times larger bandwidths than needed to suppress stimulated Raman scattering and stimulated Brillouin scattering.
