论文摘要
我们通过单阶段的光谱拓宽了Yb：kgw激光器，在单个加压的，加压的，NE-FIRE，空心核心纤维毛细管中，通过单阶段的光谱扩展来展示有效产生相干的超八杆。新兴脉冲在$ \ sim $ \ sim $ 60 dB的动态范围内跨度超过$ \ sim $ 1 phz（250 nm-1600 nm），并且出色的光束质量为结合YB：kgw Lasers与现代光场合成技术打开了大门。压缩一小部分生成的超局部到强度（8 fs，$ \ sim $ 2.4循环，$ \ sim $ 650 $ 650 $ $ j）脉冲可以方便地使用这些新颖的激光来源，并在强场物理学和Attosecond Science中使用这些新型激光源。
We demonstrate efficient generation of coherent super-octave pulses via a single-stage spectral broadening of a Yb:KGW laser in a single, pressurized, Ne-filled, hollow-core fiber capillary. Emerging pulses spectrally spanning over more than $\sim$1 PHz (250 nm- 1600 nm) at a dynamic range of $\sim$60 dB, and an excellent beam quality open the door to combining Yb:KGW lasers with modern light field synthesis techniques. Compression of a fraction of the generated supercontinuum to intense (8 fs, $\sim$2.4 cycle, $\sim$650 $μ$J) pulses allows convenient use of these novel laser sources in strong-field physics and attosecond science.
