Abstract
Differential absorption measurement for acetylene is achieved by using a Fabry-Perot laser diode in a self-seeding scheme. The two wavelengths from the laser output can be selected conveniently by switching the repetition frequency. The system has flexible wavelength tunability, larger sensitivity than that based on DFB, and high potential for multi-point, multiple gas sensing.
