摘要
利用傅立叶变换法,计算了洛伦兹、超高斯矩形超短脉冲的变换极限。计算结果表明,洛伦兹和超高斯矩形超短脉冲的变换极限分别为0.221和0.443,所得结果可用于实际洛伦兹和超高斯矩形超短脉冲特性分析。
The transform limits of Lorentz and super Gaussian rectangular line-shape ultrashort pulse laser are calculated by using Fourier transform method.It demonstrates that the transform limits of Lorentz and super-Gaussian rectangular line-shape ultrashort pulse are 0.221 and 0.443 respectively.The results obtained can be used to analyze the actual Lorentz and super Gaussian rectangular line-shape ultrashort pulses.
