Paper Abstract

We have investigated the mechanism that determines backscattering light from mirrors and diaphragms influence on intensity and frequency difference of the traveling-wave in ring laser. It is shown, that the connection of the counter waves has diffractional as well as interferention nature and is defined by parameters of the resonator mirrors and diaphragms as well as by their disposition as to the amplifying medium. Using the latter, the methods and the devices that allow us to decrease the influence of the static zone of the waves locking in on the output characteristics in 10 - 20 times have been created. The microprocessor systems for laser gyroscope generation regime support and stabilizing its parameters during exploitation were fulfilled. It is shown experimentally that a laser gyroscope with such systems has a null drift 0.005 degree/hour and a random walk 0.003 degree/sqrt (hour).
