Abstract
The paper discuss the possibility of using induction welding for creation of spectroscopic cells. This approach improves the optical quality of windows, increase the repeatability of manufacture, and simplify the creation of spectroscopic cells filled with alkali metal vapor. Described technique can be used in the rapidly developing applications, such as quantum frequency standards based on coherent population trapping (CPT). The paper presents a description of the design of cells with flat windows, the results of studies of the spectroscopic properties of the obtained cells and the results of work with the obtained cells used as part of the frequency standard.
