Abstract
The Zeeman He-Ne laser frequency stabilization system using a surface stabilized ferroelectric liquid crystal cell for polarization switching in the frequency stabilization loop is presented. Our experiments showed that two circularly polarized laser beams with on opposite sense of circularity can be switched up to 3.7 kHz rate. No additional optical components (the quarterwave and halfwave plates) were needed in switching setup. During three hours of operation the long time stability of the laser frequency of 3 multiplied by 10-8 was achieved. The laser stabilization system is suitable for the two frequency interferometer setups.
