Abstract

A relative phase shift between the different groups of excited dipoles, which appears as result of its frequency splitting due to action of a pulse of electric or magnetic fields, depends on a time, if the pulse overlaps in time with echo-pulse. As а consequence, the echo waveform is changed. The echo time form is modulated. The inverse modulation period well enough approximates Zeeman and pseudo-Stark splitting in the cases of magnetic and, therefore, electrical fields. Thus the g-factors of ground ⁴I_15/2 and excited ⁴F_9/2 optical states of Er³⁺ ion in LuLiF₄ and YLiF₄ have been measured and pseudo-Stark shift of R1 line in ruby has been determined.

Key words: photon echo / pulse frequency splitting / phase shift / echo waveform modulation / pseudo-Stark shift / R1 line / ruby
