摘要：
A small Nd: YAG laser with plano-concave resonator end pumped by a dye laser is observed to possess single Laguerre–Gauss transverse modes as the lowest-loss modes. This anomalous behavior occurs when the transverse dimension of the gain spot is much smaller than the fundamental TEM00-mode spot size of the resonator; the Laguerre–Gauss transverse-mode order varies with resonator length. © 1990 Optical Society of America.
