WebFeb 26, 2024 · A quantum cascade laser (QCL, Daylight Solutions, MIRCat-2300) with a wavelength of 6.2–8.6 µm was used as the linearly polarized light source. The polarization angle was controlled by a zero-order HWP (Altechna). Light of different frequencies was modulated using an optical chopper (Stanford Research Systems, SR540).
