2 μm波段高功率Er:Fiber/Tm:Fiber混合频率梳光源

High-power, hybrid Er:fiber/Tm:fiber frequency comb source in the 2 μm wavelength region

Florian Adler, Scott A. Diddams

摘要:

我们提出了一个2- \mum频率梳的基础上,可靠的锁模铒光纤激光器的重复频率为100 MHz。在将放大的Er:光纤梳的光谱移动到更长的波长之后,使用单包层Tm/Ho:光纤作为自泵浦前置放大器,以产生以1.93 \mum为中心的相干宽带光谱。随后,包层泵浦的Tm:光纤放大器将系统在1.96 \mum处提升到4.8 W的最大输出功率。在一个紧凑的光栅压缩器压缩后,我们的放大Er:光纤/Tm:光纤混合系统提供高达2.9 W的脉冲持续时间为141 fs。系统的梳状特性通过外差测量检查。

英文摘要:

We present a 2-\mum frequency comb based on a reliable mode-locked Er:fiber laser with 100 MHz repetition rate. After shifting the spectrum of the amplified Er:fiber comb to longer wavelengths, a single-clad Tm/Ho:fiber is used as a self-pumped pre-amplifier to generate a coherent and broadband spectrum centered at 1.93 \mum. Subsequently, a cladding-pumped Tm:fiber amplifier boosts the system to a maximum output power of 4.8 W at 1.96 \mum. After compression in a compact grating compressor, our amplified Er:fiber/Tm:fiber hybrid system delivers as much as 2.9 W with a pulse duration of 141 fs. The system's comb properties are examined via heterodyne measurement.
