从激光点火的热作用机理出发，运用传热理论，采用简化模型和近似方法，分析推导激光强度对含能材料点火的影响，得出激光二极管点火时间 ｔｉ 与激光功率密度 Ｉ０ 的关系，进而得到激光二级管点火能量 Ｅｉ 与 Ｉ０ 的关系，并和实验结果作了比较。结论： Ｅｉ 随 Ｉ０ 的增大而变小，理论与实验结果较吻合。
Based on the thermal mechanism of laser ignition, the influence of laser intensity on the ignition of energetic materials was analyzed by using heat transfer theory and simplified model and approximate method. The relationship between laser diode ignition time ti and laser power density I0 was obtained, Laser diode ignition energy Ei and I0, and compared with the experimental results. Conclusion: Ei decreases with the increase of I0, and the theoretical and experimental results are in good agreement.
