Abstract
An annular phase-locking laser with annular gain media is presented. In this paper, the light field distribution of coherent annular beam (CAB) can be given by an analytical expression based on the Collins formula. Typical numerical examples are given to illustrate the application of our analytical result and the propagation property of a CAB through a paraxial ABCD optical system.
► CAB can be obtained by annular phase-locking laser using the phase-locking method. ► A analytical expression has been given by the Collins formula. ► Propagation property of CAB through a paraxial ABCD optical system has been studied.
