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(628634nm)、橙(590597nm)和黄(564572nm)三波段激光辐射。
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.
