METHOD FOR REFERENCE RESONANCE FORMATION AT HYPERFINE TRANSITIONS FROM NORMAL STATE OF ALKALI-METAL ATOM

摘要

FIELD: electricity.SUBSTANCE: method for reference resonance formation at hyperfine transitions from normal state of alkali-metal atom based on effect of coherent population trapping in bichromatic laser field envisages selection of the excitation mode by laser having emission bandwidth "?" on the assumption that "?" ??, where ? is value of excitation spontaneous decay. The suggested method for reference resonance formation allows using cells without antirelaxation coating and buffer gas.EFFECT: cheapening of the method for reference resonance formation at hyperfine transitions from normal state of alkali-metal atom.2 dwg
