Supercontinuum (SC) generation from a highly nonlinear tellurite microstructured optical fiber with multiple rings of holes was demonstrated by pumping with a 2 μm mode-locked picosecond fiber laser. The chromatic dispersion of the fiber was measured with a homemade white-light spectral interferometer in a wide wavelength range and agreed with the theoretical calculation. Although the pumped wavelength was far from the zero dispersion wavelength, with flat dispersion profile of the fiber in the anomalous dispersion, the SC could be expanded from 650 to 2850 nm with launched pulse energy of several hundred picojoules. Simulations of SC generation agreed with the experimental results.
利用2μm锁模皮秒光纤激光器泵浦，展示了从具有多个孔环的高非线性碲酸盐微结构光纤中产生超连续谱（SC）。用自制的白光光谱干涉仪在宽波长范围内测量了光纤的色散，其结果与理论计算相符。尽管泵浦波长远离零色散波长，但由于光纤在反常色散区具有平坦的色散分布，在注入几百皮焦耳的脉冲能量时，超连续谱可从650nm扩展到2850nm。超连续谱产生的模拟结果与实验结果一致。
