三、研究方向

主要从事超快非线性光学效应以及先进光学诊断技术方面的研究：

（1）气体介质中的超快非线性光学效应

研究超快激光脉冲与物质相互作用中的非线性效应一直是光学领域的前沿和热点，其中飞秒CPA技术的发明和利用飞秒激光产生阿秒脉冲研究分布获得了2018年和2023年诺贝尔物理学奖。研究组主要关注以下几个课题：a)气体介质中飞秒激光脉冲诱导等离子体通道(laser filamentation)规律;b)飞秒激光脉冲诱导空气激光;c)原子分子电离和解离超快动力学过程探测。特别的是“空气激光”在大气遥感和燃烧诊断领域具有重大的潜在应用价值。原理上基于背向激射的单端口测量技术可以突破平方反比衰减律的限制，相比于传统技术将具有更高的测量精度和灵敏度以及更远的探测距离，因此开展该方向的研究对于大气遥感和燃烧诊断具有重要推动作用。

（2）应用于复杂燃烧场的先进光学诊断技术

温度、压强、流速和组分等热力学参数是研究燃烧化学反应机制的关键宏观参数，燃烧过程中化学反应动力学模型的实验验证、高效率低排放内燃机燃烧效率检测以及航空发动机燃烧室运行状态诊断等都需要利用非线性光学诊断技术对这些参数做精确的非接触式测量。目前的诊断技术主要依赖于纳秒激光，而超短脉冲激光由于其时间宽度更短、光谱宽度更宽，峰值功率更高，因此意味着着更高的激发效率，近年来基于超短脉冲激光的燃烧场光学诊断技术受到越来越多的重视。针对高温高压高湍流复杂燃烧流场中温度、压强、流速和组分等参数的精确测量，研究组主要研究开发以下4项技术：a)飞秒双光子吸收激光诱导荧光技术(fs-TPLIF);b)飞秒/纳秒反斯托克斯拉曼散射技术(hybrid fs/ns-CARS);c)飞秒激光诱导光栅散射/光谱技术(fs-LIGS);d)激光诱导炽光碳烟体积分数和粒径测量技术(LII)。
