In chirped pulse experiments, magnitude Fourier transform is used to generate frequency domain spectra. The application of window function as a tool for lineshape correction and signal-to-noise ratio (SnR) enhancement is rarely discussed in chirped spectroscopy, with the only exception of using Kaiser-Bessel window and trivial rectangular window. We present a specific window function, called “Voigt-1D” window, designed for chirped pulse spectroscopy. The window function corrects the magnitude Fourier-transform spectra to Voigt lineshape, and offers wide tunability to control the SnR and lineshape of the final spectral lines. We derived the mathematical properties of the window function, and evaluated the performance of the window function in comparison to the Kaiser-Bessel window on experimental and simulated data sets. Our result shows that, compared with un-windowed spectra, the Voigt-1D window is able to produce 100% SnR enhancement on average.

在chi脉冲实验中，幅度傅里叶变换用于生成频域频谱。在chi光谱中很少讨论将窗口功能用作线形校正和信噪比（SnR）增强的工具，唯一例外的是使用Kaiser-Bessel窗口和平凡的矩形窗口。我们介绍了一种专门用于chi脉冲光谱的窗口功能，称为“ Voigt-1D”窗口。窗口函数可将傅立叶变换频谱的幅度校正为Voigt线形，并提供广泛的可调性以控制最终频谱线的SnR和线形。我们导出了窗口函数的数学属性，并在实验和模拟数据集上与Kaiser-Bessel窗口进行了比较，评估了窗口函数的性能。我们的结果表明，
