摘要: 本文将PMMA和罗丹明6G的氯仿溶液虹吸到0.5 mm内径的毛细管内，待溶剂挥发后，制备成一种光纤型随机激光器，研究了光纤型随机激光器在532 nm的泵浦光作用下发射出的随机激光，中心波长位于603 nm、阈值为350 mJ/cm2，半峰全宽为4.5 nm，及脉冲宽度为15 ns。本文提出了制备一种光纤型随机激光器的简易方法，并测量了该随机激光器的基本特性。
Abstract: In this paper, a fiber-type random laser was prepared after the volatilization process of the chlo-roform solution, combining PMMA with rhodamine 6G, which was siphoned into the capillary with the inner diameter of 0.5 mm. In addition, this paper also researched the random laser which is emitted from the fiber-type random laser, inspired by the pump light of 532 nm. The result shows that the center wavelength is 603 nm, threshold is 350 mJ/cm2, full width at half maximum (FWHM) is 4.5 nm and the pulse width is 15 ns involving in the random laser. A simple method for preparing a fiber-type random laser is presented and the basic parameters of the random laser are measured.
