摘要:

利用1550 nm泵浦的倍频程超连续谱光源,通过光谱分割和再放大,获得了1110 nm附近的皮秒锁模脉冲。1110 nm的脉冲是近transform-limited,与1.7 ps的持续时间超过其1.2 nm的带宽,并表现出高的脉冲间相干。超连续谱光源和脉冲合成系统都完全在光纤中实现。多功能源的建设表明,脉冲合成切片超连续谱可能是一个有用的技术在1000 - 2000 nm的波长范围。

英文摘要:

We generate mode-locked picosecond pulses near 1110 nm by spectrally slicing and reamplifying an octave-spanning supercontinuum source pumped at 1550 nm. The 1110 nm pulses are near transform-limited, with 1.7 ps duration over their 1.2 nm bandwidth, and exhibit high interpulse coherence. Both the supercontinuum source and the pulse synthesis system are implemented completely in fiber. The versatile source construction suggests that pulse synthesis from sliced supercontinuum may be a useful technique across the 1000 - 2000 nm wavelength range.
