A new type of dye laser operating in a single-mode optical fiber has been studied. The gain is produced by surrounding a tapered section of the fiber with laser dye. Interaction of the light in the fiber with the laser dye is achieved through the exposed evanescent field at the taper waist. Low lasing thresholds (25-65 mW) are obtained as a result of the high intensities at the taper waist. These tapered fiber dye lasers combine the advantages of a laser in fiber form with the wide spectral tuning ranges provided by laser dyes. Three experiments, demonstrating low-threshold operation of a grating tuned laser, an all-fiber ring laser, and cw lasing in tapered fiber dye devices, are presented.
一种新型的在单模光纤中工作的染料激光器已被研究。增益是通过用激光染料包围光纤的锥形部分产生的。光纤中的光与激光染料的相互作用是通过锥形腰部暴露的倏逝场实现的。由于锥形腰部的高强度，获得了低激光阈值（25 - 65毫瓦）。这些锥形光纤染料激光器结合了光纤形式激光器的优点和激光染料提供的宽光谱调谐范围。本文展示了三个实验，分别证明了光栅调谐激光器、全光纤环形激光器的低阈值操作以及锥形光纤染料装置中的连续波激光发射。
