Molecular laser isotope separation

Molecular laser isotope separation (MLIS) is a technique used to separate isotopes of elements, particularly uranium isotopes, to enrich the concentration of a specific isotope—usually Uranium-235 (U-235)—over another isotope like Uranium-238 (U-238). This process is important for applications in nuclear energy and weaponry. The basic principle behind MLIS involves the use of lasers to selectively excite or ionize certain isotopes based on their unique molecular vibration and electronic transitions.
