Abstract

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