Infrared absorption spectra of the two UF 6 isotopes at 300 and 80 K. Schematic of a stage of an isotope separation plant for uranium enrichment with laser. An infrared laser with a wavelength of approx. 16 μm radiates at a high repetition rate onto a UF6 carrier gas mixture, which flows supersonically out of a laval nozzle.
Laser isotope separation, or laser enrichment, is a technology of isotope separation using selective ionization of atoms or molecules by the means of precisely tuned lasers. The techniques are: Atomic vapor laser isotope separation (AVLIS), applied to atoms; Molecular laser isotope separation (MLIS), applied to molecules
An atomic vapor laser isotope separation experiment at LLNL. The green light is from a copper vapor pump laser used to pump a highly tuned dye laser which is producing the orange light. Atomic vapor laser isotope separation , or AVLIS , is a method by which specially tuned lasers are used to separate isotopes of uranium using selective ...
Molecular laser isotope separation (MLIS) is a method of isotope separation, where specially tuned lasers are used to separate isotopes of uranium using selective ionization of hyperfine transitions of uranium hexafluoride molecules. It is similar to AVLIS. Its main advantage over AVLIS is low energy consumption and use of uranium hexafluoride ...
Separation of isotopes by laser excitation (SILEX) is well developed and is licensed for commercial operation as of 2012. Separation of isotopes by laser excitation is a very effective and cheap method of uranium separation, able to be done in small facilities requiring much less energy and space than previous separation techniques.
The singly-charged ion beam of short-lived isotopes from ISOLDE (RIB) is Doppler-tuned in resonance with the laser light provided by a continuous-wave tunable laser. Next, the beam may be neutralised, before it reaches a 1.5 m long section in which the ion or atom beam is overlapped with the laser and they interact many times (many excitation ...

One isotope, 229 Th, has a nuclear isomer (or metastable state) with a remarkably low excitation energy, [5] recently measured to be 8.355 733 554 021 (8) eV [6] [7] It has been proposed to perform laser spectroscopy of the 229 Th nucleus and use the low-energy transition for the development of a nuclear clock of extremely high accuracy.
