The development of a CO2 waveguide laser as a pump source for a CW far-infrared D2O laser is described. Performance with regard to output power and tunability is reported with special reference to the application of these lasers in over-coming the mismatch which can exist between the pump laser frequency and the vibrational absorption of the pumped molecule. This report presents summaries of the construction and performance of such lasers as well as photoconductive detectors and points the direction towards the achievement of a tunable source of pump radiation for a D2O laser. Absorption measurements in D2O using the waveguide lser are also presented. Lasing action is straight H2O and D2O lasers is also summarised over the 20 - 120 micron wavelength range.
