中文摘要：

采用沿光纤轴向倏逝波光抽运方式,研究了基于聚二甲基硅氧烷（PDMS）的回音壁模式（WGM）激光的产生长度。实验发现，以PDMS为包层的WGM激光具有较长的激光产生长度。利用这一特点，设计并制作了一块具有三个光纤沟道的PDMS基片。通过在沟道中分段填入罗丹明640、罗丹明B和罗丹明6G的乙醇增益溶液,在同一块PDMS芯片上同时获得了红（628～634 nm）、橙（590～597 nm）和黄（564～572 nm）三波段激光辐射。

英文摘要：

The produced length of whispering-gallery-mode （WGM） lasing based on polydimethylsiloxane （PDMS） is investigated. It is found that the WGM lasing has a long lasing produced length pumped by evanescent wave along the optical fiber axis. A PDMS substrate with three fiber channels is fabricated. After injecting ethanol gain solutions of rhodamine 640, rhodamine B and rhodamine 6G separately into the three channels, three-wavelength WGM lasing emission at red （628～634 nm）, orange （590～597 nm） and yellow （564～572 nm） bands is successfully observed.
