【Abstract】 Based on the para-ctal wave equation, a group of analytical solutions for amplititude and spot radius of the Gaussian beam propagation through ampered gradientindex fibers are derived. From which a series of specific solutions for Gaussian beam propagation in P8rabolic, conical and taper-like gradient index fibers are obtained in this paper.更多还原
