Mid-infrared laser-induced grating experiments of C2H4 and NH3 from 0.1-2 MPa and 300-800 K

Shin, D; Dreier, T; Danehy, Paul


Laser-induced thermal gratings (LITG) were generated in mixtures of ethylene and ammonia in nitrogen using mid-infrared laser radiation from a grating-tuned, low-pressure, pulsed (5 ms pulse width) CO2 laser, and read out with a continuous wave Nd:YLF laser. The LITG signal intensity was measured as a function of pressure (0.1-2 MPa) and temperature (300-800 K, at 0.1 and 1 MPa) by tuning the laser to the accidental coincidences of the 10P(14) and 10R(6) emission lines with molecular absorption...[Show more]
