选择含能聚合物聚叠氮缩水甘油醚（GAP）作为激光烧蚀微推力器的工质，分析了红外染料掺杂对激光烧蚀GAP工质推进性能的影响.通过对比掺杂红外染料GAP在不同激光功率密度、掺杂浓度、靶材厚度和激光烧蚀模式下的推进性能数据和烧蚀羽流，初步探索了掺杂红外染料GAP工质的推进性能优化方式.实验结果表明：透射式激光烧蚀模式下，激光能量的指数衰减特性和掺杂红外染料GAP的强黏性使得烧蚀羽流中易存在未充分烧蚀的工质；GAP的推进性能受红外染料掺杂浓度和靶材厚度的综合影响，当靶材厚度与激光吸收深度接近时，靶材充分吸收激光能量使中心烧蚀区达到化学能释放的温度阈值，同时沿激光传播方向未充分烧蚀的质量最少，此时推进性能达到最优值.反射式下掺杂红外染料的聚合物的激光烧蚀过程遵循先吸收激光能量先喷射的规律，工质分解充分，推进性能优于透射式.The energetic polymer glycidyl azide polymer (GAP) is selected as the propellant of laser ablation micro thruster, and the effect of infrared dye doping on the propelling performance of laser ablative GAP is analyzed. By comparing the propulsion performance data with the plumes of infrared dyes doped GAP under different laser intensities, doping concentrations, target thickness and laser ablation modes, the optimization of the propulsion performance of infrared dye doped GAP is explored preliminarily. The experimental results show that the exponential attenuation characteristics of laser energy and the strong viscosity of GAP doped with infrared dye in the transmission mode lead to the existence of incomplete ablative GAP in the plume. The propulsion performances of GAP are influenced by the doping concentration of infrared dye and the thickness of propellant. Only when the target thickness is close to the laser absorption depth, can the mass of incomplete ablation along the direction of laser propagation be the least and can the laser energy be fully absorbed by the propellant to make the central ablation region reach the temperature threshold of the release of chemical energy. At the same time the optimum value of propulsion performance can be achieved. The GAP doped with infrared dyes in which laser ablation process follows the rule of absorbing laser energy first and spraying first is decomposed adequately under the reflection mode and the propelling performance is better than that in the transmission mode.
