A Study of Helical Discharge Injectedd TEA CO2 Laser
In this research report, the operation principles of the CO2 laser are discussed. We start with the CO2 molecular structure, then discuss the CO2 spectra, the dipole moment, the lineshape and finally the gain. Using the principles discussed above, a low pressure discharge cell was constructed and installed in the TEA laser. This particular discharge cell was used to select single longitudinal mode operation. Such a hybrid CO2 TEA laser shows extremly narrow linewidth which is useful in many applications. This particular design has the advantage of avoiding direct damage to the Brewster windows.
