TWO-FREQUENCY STABILIZED GAS LASER Russian patent published in 1995 - IPC

FIELD: measurement technology. SUBSTANCE: two-frequency Zeeman stabilized gas laser includes active element, source of permanent axial magnetic field, power supply source and system of radiation frequency stabilization. Source of magnetic field is manufactured in the form of two plates magnetized sidewise and installed in opposition to each other with like poles in vertical plane in symmetry and in parallel to axis of active element on side of one of its ends so that length of section of mutual capillary of active element and of plates does not exceed half-length of plate. EFFECT: expanded operation field, enhanced operational stability. 1 dwg
