Comparison of Stimulated and Spontaneous Scattering Measurements of the Full Wavelength Dependence of the Raman Gain Spectrum | NIST

Summary:
Researchers at NIST have compared spontaneous and stimulated Raman scattering measurements to understand the full wavelength dependence of Raman gain spectra. They found a simple relationship between the two types of measurements, allowing spontaneous Raman spectra to be used to determine the full Raman gain dependence on both signal and pump wavelengths. This can be done using low-power diode lasers and calibrated optical spectrum analyzers, making the technique accessible and practical for various applications.
