Abstract
A double resonance infrared-far-infrared spectroscopic system is descr ibed. The variation of the 118.8 mu m wavelength gain line shape of th e methanol far-infrared laser on the diameter of the pump CO2 laser be am due to the induced nonlinear waveguiding effect has been measured. The high-frequency stability and continuous tunability of the pump CO2 lasers necessary for such measurement were achieved by frequency offs et locking them to a molecular line center stabilized reference laser. The long term frequency stability achieved for the offset locked lase rs is 24 kHz. (C) 1996 American Institute of Physics.
