The measurement of linearly polarized light rotation is the key technique in atomic magnetometer. It influences the sensitivity of atomic magnetometer directly. The basic principle of polarizer beam splitter detecting was analyzed. The ZF7 optical glass and solenoid were used to generate standard small angle based on Faraday effect. The signal of AC rotational angle was extracted by lock-in amplifier. The experiment proved that the method can measure 8×10-7rad small optical rotation. As the linearly polarized light rotation is 20mrad in atomic magnetometer, the signal to noise ratio reaches 25000.

Birefringence Effect

Experiments were performed with Fabry–Perot optical resonators in vacuum at low temperatures. Mirrors were applied on substrates of various optical materials. An infrared laser with a wavelength of 1.064 microns was used. The pump power at the maximum could reach 450 mW. The evolution of the optical properties of the FP cavity was traced in the temperature range 300–10 K. The main parameters measured were the integral characteristics of the FP resonances–sharpness (finesse) and contrast of interference. Three types of substrates were tested: a sitall, an optical glass with ultra low thermal expansion (ULE); sapphire; and calcium fluoride. During cooling, the degradation of the integral characteristics of the FP cavity was observed for the sitall mirrors due to the loss of the properties of ULE, and for sapphire mirrors due to the birefringence effect. The satisfactory constancy of the integral characteristics of the FP resonator on calcium fluoride was demonstrated in the entire temperature range studied.
