Laser absorption spectroscopy measurements of neutral N$$_2$$O in a radio frequency plasma

Infrared laser absorption spectroscopy is tested as a diagnostic for measuring neutral nitrous oxide (N $$_2$$ O) concentrations in a radio frequency (RF) plasma source. Using a quantum cascade laser tuned to an isolated rovibrational mode of N $$_2$$ O, the density of neutral mo...
