The dramatic progress in power-scaling of ultra-short pulse (USP) lasers and their continuous expansion use in industrial applications call for flexible and robust beam delivery systemes over several meters. Until recently, the maximum USP energy level that could be guided in optical fibers was limited to nano-Joule for silica-core based optical fiber, and to a few micro-Joule for hollow-core photonic crystal fiber.
In a recent collaboration, which will be presented as a postdeadline paper during the upcoming CLEO Conference in San Jose, USA, Amplitude Systemes, GLO Photonics and researchers from the GPPM group of the University of Limoges have demonstrated the delivery of milliJoule, 600 femtosecond pulses in a several meter long Kagome hollow-core-photonic-crystal-fibers, in robustly single-mode fashion. Self-compression to 50fs, and intensity-level of petawatt/cm2 were achieved.
