摘　　要：本文从实验上研究了掺杂10at%Er^(3+)离子a轴Er^(3+)YAlO_3(Er:YAP)激光器同时起振的2.7110μm,2.7299μm和2.7950μm三条谱线的偏振特性,发现2.7110μm和2.7950μm激光为线偏振光,其偏振方向平行结晶的b轴方向。2.7299μm激光为部分偏振光,椭圆的长轴沿结晶的c轴方向。文中给出了三者的输出特性。The polarization characteristics of 2.7110μm, 2.7299μm, and 2.7950μm laser emissions oscillated simultaneously in 10 at% Er^(3+) ion doped a axis YAlO_3 laser have been investigated experimentally. It has been found that the 2.7110μm and 2.7950μm laser emissions are polarized with its E vector parallel to crystallo,gra-phic b axis. While 2.7299(im laser emission is partially polarized with the long axis of ellipse parallel to crystallographic c axis. The output characteristics of these laser emissions are also given in this paper.
