为了实现高光谱分辨率的多路相干反斯托克斯拉曼散射（CARS），通常使用窄带泵浦脉冲和宽带斯托克斯脉冲。这是为了确保反斯托克斯频率和振动频率之间的对应。通过光谱干涉法检测反斯托克斯脉冲，利用宽带啁啾泵脉冲和宽带斯托克斯脉冲获得了异丙醇的高分辨率CARS光谱。利用时间分辨的反斯托克斯信号，可以去除反斯托克斯脉冲的啁啾，恢复高光谱分辨率，同时抑制非共振散射。(c) 2006年美国光学学会。
To achieve high-spectral-resolution multiplex coherent anti-Stokes Raman scattering (CARS), one typically uses a narrowband pump pulse and a broadband Stokes pulse. This is to ensure a correspondence between anti-Stokes and vibrational frequencies. We obtain high-resolution CARS spectra of isopropanol, using a broadband chirped pump pulse and a broadband Stokes pulse, by detecting the anti-Stokes pulse with spectral interferometry. With the temporally resolved anti-Stokes signal, we can remove the chirp of the anti-Stokes pulse and restore high spectral resolution while also rejecting nonresonant scattering.
