Abstract
A distributed-feedback InGaAsP diode laser has been used to perform spectra lly resolved measurements of H2O transitions near 7117 cm(-1). Line shape a nalyses of the recorded absorption spectra yielded the temperature-dependen t Ar-broadened half-widths. Room-temperature (296 K) half-widths for four t ransitions were determined with an uncertainty of + 7%/ - 5%. Temperature e xponents for three of these transitions were determined over the range of 2 96-473 K with an uncertainty of +/- 7%. (C) 1999 Elsevier Science Ltd. All rights reserved.
