在“‘星光Ⅱ”装置上，采用束匀滑的基频光打靶条件下，用光纤阵列配光学多道 分析仪在六个角度观测二次谐波发射的积分光谱，通过对共振吸收峰波长移动和峰宽度的测 量，求出；临界区域运动速度，并研究了散射光强与出射角度的关系。
In the “Star Ⅱ” device, under the conditions of beam-smoothing fundamental frequency light, the integral spectrum of the second harmonic emission was observed by optical fiber array optical multi-channel analyzer at six angles. By analyzing the resonance absorption peak wavelength Movement and peak width measurement, calculated; critical zone velocity, and studied the relationship between the scattering light intensity and the exit angle.
