Raman processes interaction (RPI) takes in the transition V2:a/spl rarr/sR(O,O) pumped by C02-10R(6). In the case of higher operating NH/sub 3/ gas pressure or lower pumping power density, the AC-Stark spectrum overlapped; that led to intense RPI, and the spikes in the spectrum appeared. The appearance of the spikes looks like an oscillation effect; in fact, it would be a kind of fine-structure of AC-Stark spectrum in a special case of RPI. The spikes looked like a flag of RPI, the more the spikes appeared, the stronger the RPI would be. We did not find the spikes in other transitions, except the a/spl rarr/sR(O,O) transition. This means that the spike effect not only is a function of the laser operating parameters, such as the pumping power and operating gas pressure. but also a function related to a complicated physical process, which relates to the molecular energy levels and the transition dipole moment.
