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.KeywordsSignal AverageDrive CurrentPeltier ElementPresent Paper ReportTemperature TuningThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
