The model of magnetically confined discharge CO laser

A model for magnetically confined discharge carbon monoxide laser is presen ted. Electron energy distribution function, the influence of the magnetic f ield on electron impact excitation, the vibration-to-translation and vibrat ion-to-vibration excitation rates of CO molecule are discussed. The vibrati onal-state populations of CO molecule and small-signal gain with magnetic f ield are calculated and studied also. After a magnetic field has been added , there appears a hole in the distribution of the vibrational-state populat ions of CO molecule and the small-signal gain is higher in this region.
