"Scale factor" of laser gyro
Momentum of pulse of light and the sense of so-called "scale factor" of laser gyro (LG) are determined on the base of semiclassical theory. Quantum restriction of Sagnac effect and additive error of "scale factor" of LG are determined. Here is shown that "dead zone" on output characteristics of LG is conditioned with precession of momentum of forces vector around the vector of angular velocity, acting on ring baghron of light inside the LG.
