    Notes: Abstract Line dependent saturation has been studied in a CO2 waveguide laser, operating cw in 100 lines of the 9 μm and 10 μm bands. In both bands, for constant discharge conditions, the saturation intensity is found to be strictly inversely proportional to the small signal gain for lines in the range J=2 to J=48 in both the P and the R branches. For lasers operating well above threshold this implies an output power which is essentially independent of the line number. The effect is verified experimentally, and discussed theoretically.

    Second-harmonic and sum-frequency generation in AgGaSe2 with tunable waveguide CO2 lasers (1995)
    Springer

    Notes: Abstract A tunable source is described, giving extensive coverage of a spectral region around 2000 cm−1. A frequency self-calibration routine allows for the recording of Doppler-limited absorption profiles with an absolute accuracy of better than 10 MHz. The applicability of the source is demonstrated through measurements on the12C16O,12C17O, and12C18O isotopomers. Collision-broadening parameters and line strengths are determined, some of the data showing evidence of motional narrowing. Sensitivity limits are determined for linear absorption measurements as well as for photoacoustic absorption, and the feasibility of monitoring all three isotopomers with ppm sensitivity is demonstrated.
