Abstract: We report a method for measuring complex coupling coefficients in a ring resonator of a laser gyroscope. It is shown how, using the results of the measurements, to predict the values of the lock-in threshold and nonlinear distortions of the scale factor of a laser gyroscope at the stage of assembly and adjustment of the ring resonator and, in particular, to detect the presence of dust particles in the working areas of the mirrors. The possibilities of using this method to optimize the process of sputtering multilayer mirrors of a laser gyroscope are discussed.

Keywords: ring laser, ring resonator, laser gyroscope, backscattering, complex coupling coefficients, dissipative and conservative components, lock-in threshold, nonlinear distortions of the scale factor.
