Abstract : Relaxation behavior of 17 water vapor laser lines in the range 23 to 79 microns wavelength, obtained with a split-discharge laser, is presented. Two discharges are incorporated in the same laser resonator and pulsed at varying times. The laser signal produced by the first discharge then probes the decaying second discharge at subsequent time intervals. Measuring the absorption as a function of time permits one to measure relaxation rates and suggests processes going on at different times. A fall out of this work is some new gain measurements on the 27.97 and 118.59 micron lines. (Author)
