Abstract: The kinetics of the processes occurring in an O2–I2–He–H2O gas flow in which photodissociation of molecular iodine at a wavelength close to 500 nm and excitation of atomic iodine on the 2P1/22P3/2 transition by narrow-band radiation near 1315 nm are implemented successively has been analysed. It is shown that implementation of these processes allows one to form an oxygen-iodine medium with a high degree of dissociation of molecular iodine and a relative content of singlet oxygen O2(a1Δ) exceeding 10%. Having formed a supersonic gas flow with a temperature ≈100 K from this medium, one can reach a small-signal gain of about 10-2 cm-1 on the 2P1/22P3/2 transition in iodine atoms. The specific power per unit flow cross section in the oxygen-iodine laser with this active medium may reach ≈100 W cm-2.

Keywords: optical pumping, singlet oxygen, iodine atom, oxygen-iodine laser, diode laser.
