Abstract

In this article we explore the possibility of utilizing 1560 nm nanosecond dissipative soliton resonance pulses for generation of supercontinuum radiation in a standard singlemode fiber. The source is based on a non-complex, all-in-fiber dissipative soliton resonance mode-locked laser and two sections of fiber amplifiers, boosting the peak power and pulse energy to 147 W and 0.42 µJ, respectively. Pulses with a repetition rate and pulse duration of ∼1.01048 MHz and 2.67 ns, respectively, were injected into a standard singlemode fiber (SMF-28, Corning) with lengths between 100 m and 600 m. Induced Stimulated Raman Scattering effect resulted in a broadening of the pulse spectrum from the initial 1560 nm, up to ∼2100 nm. Our results are the first demonstration of using high-energy nanosecond pulses from a non-complex, all-in-fiber dissipative soliton resonance mode-locked laser in a frequency conversion process in a standard singlemode fiber. The proposed approach delivers an alternative solution to broadband light generation using complex nanosecond laser sources.

利用 1560 纳米波长的耗散孤子共振脉冲在单模光纤中产生超连续介质
本文探讨了利用 1560 nm 纳秒耗散孤子共振脉冲在标准单模光纤中产生超连续辐射的可能性。该光源基于非复杂的全光纤耗散孤子共振锁模激光器和两段光纤放大器,可将峰值功率和脉冲能量分别提高到 147 W 和 0.42 µJ。将重复率和脉冲持续时间分别为 1.01048 MHz 和 2.67 ns 的脉冲注入长度介于 100 m 和 600 m 之间的标准单模光纤(SMF-28,康宁公司)。诱导受激拉曼散射效应使脉冲光谱从最初的 1560 nm 扩展到 2100 nm。我们的研究结果首次证明,在标准单模光纤的频率转换过程中,可以使用来自非复合全光纤耗散孤子共振模式锁定激光器的高能纳秒脉冲。所提出的方法为使用复杂纳秒激光源产生宽带光提供了另一种解决方案。
