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 ...
Isotope separation is the process of concentrating ... (atomic vapor laser isotope separation). This method has only been developed as laser technology has improved ...
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
The atomic vapor laser isotope separation (AVLIS) process uses the hyperfine splitting between optical transitions in uranium-235 and uranium-238 to selectively photo-ionize only the uranium-235 atoms and then separate the ionized particles from the non-ionized ones.
An atomic vapor laser isotope separation experiment at LLNL. Green light is from a copper vapor pump laser used to pump a highly tuned dye laser which is producing the orange light. Dye lasers are very versatile. In addition to their recognized wavelength agility these lasers can offer very large pulsed energies or very high average powers.
Copper vapor lasers are used in some machining and laser cutting applications. They can also be used in AVLIS isotope separation systems. In the AVLIS application the copper laser is used to excite tunable dye lasers. A review on copper-laser-pumped dye lasers is given by Webb in High Power Dye Lasers. [7]
Additionally, Eberly has studied atomic vapor laser isotope separation. [ 7 ] [ 8 ] In 2003, he discovered the phenomenon of crystallization in time for highly excited states of atoms.
