Title: PRESSURE BROADENING OF THE $O_{2}$ B BAND MEASURED BY CAVITY RING-DOWN SPECTROSCOPY
Creators: Robie, Daniel C.; Seiser, N.
Issue Date: 1996
Abstract: We have used cavity ring-down spectroscopy to measure pressure-broadening coefficients for several rotational lines in the atmospheric B band of $O_{2}$ at 688 nm. Collisional partners of the $O_{2}$ include $O_{2}$, $N_{2}$, and Ar. Total pressures range up to 2 atm; at that pressure, the self-broadened linewidth is $0.3 cm^{-1}$, about twice the laser bandwidth. Comparisons with previous measurements by other techniques will be discussed.
