Transverse modes of an apertured laser.


Modes of a diaphragmed laser are expressed as linear combinations of Laguerre-Gauss functions and computed from the resonance condition. Hard and soft apertures are considered. Explicit results are given in both cases for the phase and amplitude distributions inside and outside a plano-concave cavity and for the three modes having the lowest losses. Deformations of modes with the diameter of the diaphragm are also given, showing the evolution of lateral lobes.
