Abstract:
Shifted excitation Raman difference spectroscopy (SERDS) with alternating dual-wavelength excitation enables extracting Raman signals that provide molecular target information from background disturbances such as ambient light and fluorescence [1]. Simultaneous dual-wavelength emission is needed for the generation of THz emission to obtain structural target information [2]. A diode laser suitable for such applications should provide dual-wavelength laser emission with a few hundred milliwatts in the near-infrared spectral range.
