(a) Spectra of the excited SHG and the FW laser at a FW laser power of 87.12 μW. The inset shows that the SHG signal has a square power dependence on the FW laser. (b) Polarimetric plot of the total SHG signal under parallel polarized excitation (TM). (c) Total SHG signal as a function of the FW polarization angle.
