研究了一种工作在镱增益带长波长边缘的高功率掺镱光子带隙光纤放大器。光子带隙的光谱滤波效应有效地抑制了在常规镱增益波长处的放大的自发发射，从而使得能够在1178 nm处进行高功率放大。在1178 nm处获得了167 W的最大输出功率，斜率效率为61%，饱和增益为15 dB。
An ytterbium-doped photonic bandgap fiber amplifier operating at the long wavelength edge of the ytterbium gain band is investigated for high power amplification. The spectral filtering effect of the photonic bandgap efficiently suppresses amplified spontaneous emission at the conventional ytterbium gain wavelengths and thus enables high power amplification at 1178 nm. A record output power of 167 W, a slope efficiency of 61% and 15 dB saturated gain at 1178 nm have been demonstrated using the ytterbium-doped photonic bandgap fiber.
