$${\text {CO}}_2$$ laser system design for efficient boron isotope separation by the method of selective laser-assisted retardation of condensation

Abstract

A cheap and efficient production of boron isotopes is important for providing further progress in nuclear engineering, semiconductor industry, and nuclear medicine. Motivated by this problem, we consider the $${\text {CO}}_{2}$$ laser system designed to separate boron isotopes by the method of laser-assisted retardation of condensation. Values of the basic parameters for this system, such as an acceptable variation range of the laser operating pressure, mode locking laser system design, and estimation of an acceptable interval for the variation of laser intensity for various positions of the photo-absorption lines of $${\text {BCl}}_3$$ , corresponding to ambiguity of available experimental data, are found. To calculate them, a new formalism, which takes into account spectral shape of photo-absorption cross section and laser pulse emission spectrum, is developed. Conclusion that the three-line excitation is the most efficient one has been derived.
