Abstract
High power ultrashort pulsed fiber laser are used in a wide range of applications such as micromachining, sensing, texturing and biophotnics. The main challenge today is to find the best solution to transport the beam over a several meter-long optical path. Recent developments on Kagome-lattice hollow core photonic crystal fibers (HC-PCF) with large core which exhibit broadband guidance, low spatial overlap with silica and low attenuation open new perspectives [1]. In this paper, we demonstrate fiber delivery of high energy and high power ultrashort pulses which are used to realize micromachining on several materials.
