Abstract: We have constructed a mathematical model of an intracavity difference-frequency generator based on a dual-wavelength semiconductor disk laser in the form of a time-delay dynamic system. Steady-state lasing (the equilibrium state of the dynamic system), its stability, and also transient dynamics after switching on the primary optical pump source are investigated. It is shown that the equilibrium state is stable in a wide range of parameters, which is of interest for possible applications of such a generator.

Keywords: nonlinear-optical interaction, difference-frequency generation, mid-IR range, semiconductor disk laser.
