abstract

  • The recently suggested mechanism of I2 dissociation in the chemical oxygen-iodine laser (COIL)[K. Waichman, BD Barmashenko, and S. Rosenwaks, J. Appl. Phys. 106, 063108 (2009) 10.1063/1.3213380; K. Waichman, BD Barmashenko, and S. Rosenwaks, J. Chem. Phys. 133, 084301 (2010)] 10.1063/1.3480397 was largely based on the suggestion of VN Azyazov, S. Yu. Pichugin, and MC Heaven [J. Chem. Phys. 130, 104306 (2009)] 10.1063/1.3081454 that the vibrational population of O2 (a) produced in the chemical generator is high enough to play an essential role in the dissociation. The results of model calculations based on this mechanism agreed very well with measurements of the small signal gain g, I2 dissociation fraction F, and temperature T in the COIL. This mechanism is here revisited, following the recent experiments of MV Zagidullin [Quantum Electron. 40 …
