从理论上定义了基于高斯脉冲成分分析的激光脉冲时域响应的偏离度参数,并且通过实验验证了该定义的有效性。利用高速光电探测系统测量入射和出射的微秒量级激光脉冲的实际能量分布,在3%的容差范围内对能量分布进行高斯脉冲分量拟合,通过对比各独立高斯成分的归一化强度经系统后的理想值与真实值,计算得到偏离度。在该定义下.通过分析各高斯分量的权重演化以及新分量的成因,不仅可以研究光场与系统相互作用的物理机制,而且为系统的优化设计提供帮助。
Define the deviation parameter of laser pulse time-domain response based on Gaussian pulse component analysis theoretically, and the validity of this definition is verified by experiments. The high-speed photodetection system was used to measure the actual energy distribution of the incident and exited microsecond laser pulses. The energy distribution was fitted to the Gaussian pulse components within a tolerance of 3%. By comparing the normalized intensity of each independent Gaussian component After the system of the ideal value and the real value calculated deviation. Under this definition, we can not only study the physical mechanism of the interaction between light field and system, but also help to optimize the system by analyzing the weight evolution of each Gaussian component and the origin of new components.
