摘要
测量了基频激光打靶条件下不同角度的二次谐波光谱 ,得到了谐波光强随发射角度的变化关系以及能量转换效率随激光强度变化的曲线 .
Time integrated spectra of second harmonic (2 ω ) light emission from plasmas produced with 1.053μm laser are simultaneously measured at several scattering angles.By analyzing the relationship between scattering energy and scattering angle,also by analyzing the total 2 ω light intensity as a function of incident beam intensity,we found that the Langmuir turbulence,which is produced by cascade of parametric decay instability,plays an important role in the laser plasma interaction.
