摘要：

A novel method for discriminating and selecting a specific high order mode is presented. It is based on introducing spiral phase elements into a laser resonator, so as to improve the output beam quality over that when the laser operates with multi-modes, and yet maintain a relatively high output power. The theoretical analysis, along with experimental results with CO2 and Nd:YAG lasers are presented. The results reveal that a 50% increase of laser output power over that operating with TEM00 mode is possible. (C) 1999 Elsevier Science B.V. All rights reserved.
