从理论上分析了包层抽运的固体芯光子带隙喇曼光纤放大器作为功率扩展的可能候选者。对模场直径为46微米、包层直径为250微米的光纤进行了计算，在泵浦波长为1.567微米的情况下，在第一斯托克斯波长和第二斯托克斯波长分别显示了0.12分贝/千米和10分贝/米的限制损耗，同时在实际的盘绕结构中保持了低损耗和大的模式面积。模拟了基于该光纤的拉曼放大器，其输出功率为85kW，光转换效率为78%，最大热负荷为130W/m，长度为235m。
Cladding-pumped solid-core photonic bandgap Raman fiber amplifiers are analyzed theoretically as possible candidates for power scaling. An example fiber design with a mode field diameter of 46 µm and a cladding diameter of 250 µm is calculated to exhibit 0.12 dB/km of confinement loss at the first Stokes wavelength and >10 dB/m at the second Stokes wavelength for a pump wavelength of 1.567 µm while maintaining low loss and large mode area in realistic coiling configurations. A Raman amplifier based on this fiber with 85 kW of output power, 78% optical conversion efficiency, a maximum heat load of 130 W/m, and a length of 235 m is simulated.
