Abstract
Wavelength modulation spectroscopy by the use of a tunable optical filter was applied to an intra-cavity fiber laser gas sensor. The optimum pump power and the modulation amplitude that maximized the signal-to-noise ratio were found. A minimum detectable gas (C2H2) concentration of 1000 ppm was experimentally achieved.
