Abstract
In spectroscopic measurements, signal averaging by repeated frequency sweeps of the light source is a powerful means of improving signal-to-noise ratios. It was recently shown that the operating voltage of a diode laser, when its drive current is held constant during temperature tuning, is a good monitor of the frequency /1/. This implies that signal averaging is possible by recording the spectra as a function of the operating voltage. The present paper reports on the first demonstration of signal averaging in diode-laser spectroscopy by this method.
