Gas temperature and water concentration are measured by a tunable diode laser sensor using a single laser near 1.4 m. Temperature is determined from the ratio of absorption of a H 2 O line pair near 7079.176 and 7079.855 cm -1 , which are chosen using some selected criteria. The second harmonic dete
