Paper Abstract

The factors of Chemical Oxygen-Iodine Laser (COIL) resonator expanding angle design are analyzed in this paper. It is shown that the primary factor is the rate of the releasing heat from the near resonant energy transfer reaction between O2(1Δ) and I at the resonator entrance with the laser extracting. It is a characteristic of COIL that the rate of the releasing heat with lasing is bigger than without lasing. A slightly bigger resonator expanding angle than that of constant pressure operating condition is sufficient to avoid the shock wave appearance.
