Error analysis of peak power formula in pulsed lasers

College of Applied Sciences, Beijing University of Technology, Beijing 100124, China

摘要

摘要:为分析脉冲中常用峰值功率公式的误差，对高斯脉冲、双曲正割脉冲、洛仑兹脉冲、非对称双曲正割脉冲的常用峰值功率公式的误差进行了解析计算。结果表明：高斯脉冲、双曲正割脉冲、洛仑兹脉冲、非对称双曲正割脉冲中，常规峰值功率公式的结果与实际峰值功率的误差分别为6.3%，13.6%，22.1%，20.9%。在具体实验基础上采用数值方法分析了非常规脉冲的情形，给出了精确计算峰值功率的方法。

Abstract:To investigate the errors brought about by common formula of peak power in pulsed lasers, the peak powers of pulsed laser types of Gaussian, Sech2, Lorentzian, asymmetric Sech2 were calculated analytically. The results demonstrate that the errors introduced by common formula of peak power for Gaussian, Sech2, Lorentzian, asymmetric Sech2 were 6.3%, 13.6%, 22.1%, 20.9% respectively. Furthermore the peak power of irregular pulse was discussed by numerical method based on practical experiments and a method to precisely calculate peak power was proposed.
