Paper Abstract

A model is proposed of passive Q-switching in a laser by a crystalline switch with phototropic centers. Expressions for the output energy and duration of a giant pulse are derived taking account of the geometric factor representing the distribution of the orientations of these centers relative to the crystal lattice of the passive switch. The calculated results are in agreement with those obtained in an experimental investigation of passive Q-switching in a neodymium laser with a switch based on a doped LiF:F2- or Cr4+:YAG crystal.
