Abstract
We report on damage-free fiber-guidance of milli-Joule energylevel and 600-femtosecond laser pulses into hypocycloid core-contour Kagome hollow-core photonic crystal fibers. Up to 10 meter-long fibers were used to successfully deliver Yb-laser pulses in robustly single-mode fashion. Different pulse propagation regimes were demonstrated by simply changing the fiber dispersion and gas. Self-compression to ̃50 fs, and intensity-level nearing petawatt/cm2 were achieved. Finally, free focusingoptics laser-micromachining was also demonstrated on different materials.File | Dimensione | Formato | |
