利用掺Yb双包层光纤对LP11模芯截止波长大于入射波长的径向偏振激光光束进行了放大。在保持强度和偏振分布的同时，放大了光束的功率。随着输入功率的增加，放大的自发辐射变得可以忽略不计。测得斜率效率为48%，输出功率为1.1W。
Amplification of a radially polarized laser beam is demonstrated by use of an Yb-doped double-clad fiber whose core cutoff wavelength for the LP11 mode is larger than the wavelength of the input beam. The beam power is amplified while maintaining the intensity and polarization distributions. The amplified spontaneous emission becomes negligible with increasing input power. The measured slope efficiency is 48%, and the output power is 1.1 W.
