Abstract
The small-signal gain spectrum of CO2 lasers operated at pressures of <5 atm is strongly modulated by the individual rotational transitions. Above 5 atm, however, pressure broadening begins to cause significant overlap of the gain. By 10 atm the gain modulation is only ~10%, and the gain can be roughly described by four broad nearly featureless lines due to P and R branches associated with the (001-100) and (001-020) vibrational transitions. These four lines each have sufficient bandwidth for amplification of pulses as short as 1 psec.
