Abstract : A simplified analytical model of a diffusion-type HF chemical laser is presented. In this device, H2 is diffused into a supersonic stream to react with F atoms and form vibrationally excited HF that is made to lase. The reaction between H2 and F is assumed to commence at a flame sheet. A two-vibrational level model for the HF molecule is adopted. The dependence of laser amplifier and oscillator performance on diffusion rate, forward reaction rate, collisional deactivation rate, and radiative deactivation rate is determined. (Author)
