Wavelength Modulation in Tunable Diode Laser Photoacoustic Spectroscopy

Not Accessible

Your library or personal account may give you access

Abstract

Wavelength modulation waveforms were studied in tunable diode laser photoacoustic spectroscopy by way of simulations and experiments. The modulation waveforms were sinusoidal, triangular, shaped, and quasi-square waves. The quasi-square waveform gave the largest signal-to-noise ratio.
