  By realizing the project of intensive
  $\gamma $ beams with large energy (necessary for Photon Colliders) an
essential flux of light Goldstone particles (LGP - axions, arions, familons,
majorons) can be generated. The probability of LGP production is calculated for
different densities of laser photons in the conversion region (with absorption
of one or several laser photons). The method for observation of LGP via its
absorption in the matter is also presented.
