Cavity enhanced absorption spectroscopy measurements of pressure-induced broadening and shift coefficients in the upsilon (1)+upsilon (3) combination band of ammonia

Abstract:

Cavity enhanced absorption spectroscopy is performed using an external cavity diode laser operating around 1516 nm. We demonstrate a sensitivity of 6×10-8 cm-1∈Hz-1/2 and utilise a simple method to measure pressure-induced broadening and shift coefficients. The broadening and shift coefficients for six gases (helium, neon, argon, xenon, oxygen and nitrogen) have been determined at room temperature for four transitions in the υ 1+υ 3 combination band of ammonia. Comparisons of the broadening c...
