研究了二极管激光诱导含能材料点火的化学反应机理,建立了时间分辨光谱测试系统,测量了在激光作用下B /KNO3 的光谱发射历程,探测到了二极管激光作用下一些中间产物,而且可以观察到二次点火现象。实验和计算结果表明: B /KNO3 在激光作用下的点火机理属于热点火机理。
Abstract:
An igniting and testing system are set up in order to deep ly understand the reactingmechanism of energetic materials induced by laser diode. Emission spectrum of B /KNO3 induced by laser diode is measured. There is a twice-ignition phenomenon. Some intermediate products are detected. The results suggest that the laser diode ignition is thermalmechanism.
