| 摘 要： | 分析了在激光模拟单粒子效应试验中激光波长、束斑大小、脉冲能量、脉冲宽度等脉冲激光参数对阈值能量的影响。其中，利用A．Douin理论预测的单粒子翻转（SEU）激光阈值能量与作者的试验结果相吻合，同时，采用阈值LET等效原理对激光诱发单粒子翻转的脉冲阈值能量标定系数计算的结果表明：波长为1064nm的皮秒激光脉冲阈值能量等效重离子LET值与器件敏感体积的电荷收集深度无关。

| Abstract: | Effects of pulsed laser parameters such as laser wavelength,beam spot size,pulse energy and pulse duration on threshold energy in laser simulating Single Event Effect testing are analyzed. The Single-Event-Upset （SEU） pulsed laser threshold energy predicted by A. Douin＇s theory accords well with the results acquired in author＇s testing. At the same time, the calibrating coefficient of pulse threshold energy in SEU induce by laser calculated with threshold LET equivalence principle shows that the 1 064 nm picosecond pulsed laser threshold energy-equivalent heavy-ion LET value is independent of charge collection depth in device sensitive volume. |
