本文分析了激光激发原子中荧光产生的光脉冲的高次模的泵浦效率。检查三个高阶模TE 01、TM 01和HE 21的模激发效率，并与光纤基模HE 11的激发效率进行比较。结果表明，高阶模的抽运率一般比基模的抽运率高5-10倍。得出的结论是，与泵浦高阶模式的纳米光纤可以发挥接口的作用，允许一个传输存储在光激发原子的电磁能量到光纤内传播的光学模式。
The pumping efficiency of the higher-order modes of an optical nanofiber by fluorescence excited in atoms by laser light is analyzed. The mode excitation efficiency is examined for three higher-order modes TE01, TM01 and HE21 and compared with the excitation efficiency for the fundamental fiber mode HE11. It is shown that pumping rates for the higher-order modes of an optical nanofiber are generally 5–10 times higher than that for the fundamental mode. It is concluded that optical nanofibers with pumped higher-order modes can play the role of interfaces allowing one to transfer electromagnetic energy stored in optically excited atoms into the optical modes propagating inside the fibers.
