Abstract

We present a direct comparison of the measured spontaneous Raman spectra and the measured stimulated Raman gain from a pump laser. We confirm that the spontaneous Raman spectrum is related to the stimulated Raman gain spectrum through a simple Bose-Einstein temperature factor. Given this simple relation, the full dependence of the Raman gain on both the signal and pump wavelength can be extracted directly from spontaneous Raman spectra, which are easily generated with a low-power (few mW) diode laser and calibrated optical spectrum analyzer.
