Spectroscopy of Stoichiometric Laser Materials: Excitons or Incoherent Transfers?

  • F. Auzel
Part of the NATO Advanced Science Institute Series book series (NSSB, volume 88)


In the so-called stoichiometric laser materials, a high concentration of active ions is necessitated by the micrometric dimensions of the laser. Such a high concentration leads to strong interactions between ions giving rise to a self-quenching process explained either in an energy transfer model with fast diffusion among donors before transfer to a quenching center or in an excito-nic model with exciton annihilation at the sample surface. Theoretical and experimental aspects of the spectroscopic and dynamical studies shall be presented with reference to usual laser materials along with a general discussion of self-quenching.
