Abstract

The paper is devoted to the study of the properties and characteristics of isotope filters that filter ultrathin components of the ground state in rubidium atoms located in the absorption cell of a physics package from the composition of a quantum frequency standard on a rubidium gas cell with an optical pumping source on an electrodeless spectral lamp, in order to study the possibility of reducing the effect of temperature fluctuations of an electrodeless spectral lamp on shifts of the resonant frequency in the cell absorption depending on the studied properties of the isotope filter. The results are given of the complex studies of the optical pumping and frequency shifts efficiency in the absorption cell using isotope filters depending on the argon pressure in them in the range of 100–220 torr and their temperature 82–92°С. Based on the study of the data obtained, it was concluded that the minimal effect of temperature fluctuations of an electrodeless spectral lamp on the shifts of the absorption cell resonance frequency is provided when using a filter with a pressure of 150 torr of argon at a temperature of 82°С.

AB  - The paper is devoted to the study of the properties and
characteristics of isotope filters that filter ultrathin components
of the ground state in rubidium atoms located in the absorption cell
of a physics package from the composition of a quantum frequency
standard on a rubidium gas cell with an optical pumping source on an
electrodeless spectral lamp, in order to study the possibility of
reducing the effect of temperature fluctuations of an electrodeless
spectral lamp on shifts of the resonant frequency in the cell
absorption depending on the studied properties of the isotope filter.
The results are given of the complex studies of the optical pumping
and frequency shifts efficiency in the absorption cell using isotope
filters depending on the argon pressure in them in the range of
100–220 torr and their temperature 82–92°С. Based on the study of the
data obtained, it was concluded that the minimal effect of
temperature fluctuations of an electrodeless spectral lamp on the
shifts of the absorption cell resonance frequency is provided when
using a filter with a pressure of 150 torr of argon at a temperature
of 82°С.
