the Enhanced Inhomogeneous Broadening Effect and Laser Signature From a Waveguide CO2
The waveguide CO2 Laser possesses a distinctive feature, although the gain profile is Doppler broadened it appears as homogeneously broadened and exists inhomogeneous broadening, which typically is viewed as disturbing element. We can induce its enhanced inhomogeneous broadening phenomenon by a choice of optimal partial gas composition ratio, gas pressure and pumping speed. Another specific phenomenon, which appears in tuned waveguide CO2 lasers, called a laser signature, and it is a calibration by using half -wavelength scan based on servomechanism. The two phenomena are discussed and indicated their potential application in the simultaneous detection of multi-gas based photoacoustic spectroscopy or other infrared spectra in this paper.
