Abstract
A model is proposed of passive Q switching in a laser by a crystal swi tch with phototropic centres, Expressions for the output energy and du ration of a giant pulse are derived taking account of the geometric fa ctor representing the distribution of the orientations of these centre s relative to the crystal lattice of the passive switch, The calculate d results are in agreement with those obtained in an experimental inve stigation of passive Q switching in a neodymium laser with a switch in the form of a doped LiF:F-2(-) or Cr4+:YAG crystal.
