Extreme resolution of the laser pumped alkaline vapor self-oscillating magnetometers

The results of analytic study of optical pumped spin generator with alkaline vapors in saturation mode are presented. According to analysis of stochastic equations for amplitude and frequency fluctuations we have obtained equations for natural and technical line width which determine resolution of spin generator. Resulting dependences are compared with the same ones for spin generator where the mechanism of amplitude limiting is based on nonlinearity of the amplifier feedback.
