Atomic vapor laser isotope separation process

Claim 1

In an atomic vapor laser isotope separation process, a laser spectroscopy system comprising a first reference laser for generating a first laser beam having a first reference laser frequency, a second tunable laser for generating as an output a plurality of second laser beams having a range of laser frequencies, means for sweeping said second laser to generate said second laser beams including phase locked loop control means for adjusting said output of said second laser to predetermined frequency outputs, said control means including means for varying the frequency of said second laser, means for coupling said second laser beams into an atomic vapor having spectral isotope components, means for heterodyning said first referenced laser frequency and frequencies of said second laser beam to form heterodyned frequencies, and means for processing said heterodyned frequencies to determine said spectral components of said atomic vapor.
