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