Abstract
In optical pumping experiments using a laser, beam polarization can be modulated with the help of an electrooptic modulator device. This technique has been applied to pump 4He(23S1) metastable atoms. New resonances, never observed before, has been studied theoretically and experimentally versus geometric and modulation parameters and an application to high sensitivity magnetometer is presented.
