In order to develop laser modes in stable resonators,an analytical method was adopted to resolve the field distribution of the laser modes in stable optical resonators.The expressions for the laser modes were derived after seeking simple solutions to Maxwell's equations.The plots of the field intensity distribution corresponding to some laser modes in plan-concave Nd∶ YAG laser were shown.The theory of laser modes in stable resonators was enhanced.
