High-resolution CARS measurements of temperature profiles and pressure in a tungsten lamp.
We use high-resolution coherent anti-Stokes Raman spectroscopy to measure the temperature profile and pressure in a nitrogen-filled tungsten lamp. Using a modified exponential-gap model for the J-dependent collisional-broadening coefficients, we obtain good fits to the experimental spectra, yielding spatially resolved temperatures and pressures with an accuracy of +/-5%.
