Abstract
FM modulation is investigated as a technique for accurately measuring the linewidths of Lorentzian resonances observed by stimulated Raman scattering difference frequency tuning. A normalized linewidth is obtained from the ratio of the nth to the ( n + 1)th harmonic content of the detected signal. Possible applications in temperature measurement are discussed.Keywords
