Abstract
The same quantum cascade laser spectrometer working around 9 μm was used in both continuous-wave and pulsed modes to compare their own characteristics. The laser emitting in continuous-wave mode was mainly used to study some spectroscopic parameters of SO2 ro-vibrational lines. This work demonstrates the necessity to use new calculations previously developed instead of conventional databases such as HITRAN. In addition, the same laser emitting in pulsed mode with long pulses (600 to 900 ns) was used to record SO2 spectra with the intrapulse technique. This work permits us to make comparisons about those two modes of emission for the development of future spectrometers.
