Active gas mixtures of iodine photodissociation lasers are used as an example to show that, in thermodynamically nonequilibrium media when the rates of the chemical reactions depend on the electromagnetic field intensity, stimulated light scattering by thermal waves excited as a result of the enthalpy of the thermodynamically nonequilibrium medium may be observed. A theoretical analysis is made of the scattered-light spectrum. It is found that the light is amplified at the anti-Stokes frequency and the stimulated scattering gain under conditions typical of iodine lasers for an active gas pressure mixture of approx. 0.5 atm may reach 100--400 cm/mW.
