Kinetics of the decomposition of CF3CF2Cl at 50 torr by a cw CO2 laser have been studied over a range of laser frequencies extending 36 cm−1 below an absorption band center at 980 cm−1. At constant translational temperature, the change in the rate constant with laser frequency is a factor of 100, comparable to the effect previously observed in CF2ClCF2Cl. Arrhenius plots show an activation energy of 86.2 kcal/mole, independent of frequency.

Good Agreement

A theoretical model of a waveguide CO2-laser was made to optimize the dimensions of the waveguide tube and resonator, i.e., to obtain the best mode structure while maximizing the output power. The results were used to design and build the laser itself around a quartz waveguide tube of 25.5 cm and 3 mm inner diameter. A simple, low-cost, and efficient VMOS based current stabilization was applied, which stabilized the current to within ?0.5%. The working laser frequency selection and/or frequency stabilization was controlled by a piezo micro-positioner, which was coupled with an output power meter via a PC computer and driven by self-made software developed for the purpose. The experimental test of the laser showed good agreement with the model.
