Abstract

Two novel magnetooptic sensors are proposed which are based on mutual compensation of external field-induced linear or circular birefringence. One is based on mutual compensation of the external field-induced linear birefringence produced by both magnetooptic Cotton-Mouton effect and electrooptic Kerr effect. The other one is based on mutual compensation of the external field-induced circular birefringence in crystals exhibiting both Faraday magnetooptic effect and electrogyration effect, such as lead molybdate (PbMoO₄) crystal. The 50Hz ac magnetic field in the range of 167Gs was measured by means of electrogyration compensation. Compensating voltage was about 16.5V/Gs for single lead molybdate crystal with a length of 5mm along its principal optical axis. The two proposed magnetooptic sensors can be used in the closed-loop measurement of magnetic field.
