Among the different types of Lasers, fibre lasers are, both as research and commercially, the youngest, yet the fast growing type of laser due to several factors. This Action will be the first arena where experts in fundamental material science, established laser and component groups, fibre laser manufacturers and end-users will be able to actively interact, share know-how and focus on common goals. We do expect to boost a series of innovations in the field. Among them we aim to cover the 3-6 micron wavelength interval, and beyond, to support mid-infrared applications and to enhance fibre performance to cover more efficiently visible and ultra-violet wavelength generation for biophotonics and healthcare. The Action will also investigate glass material and fibre design to overcome the actual limitation in output power. The improvements will mainly boost healthcare to benefit wide society and EU manufacturing to retain and increase manufacturing workforce within EU. The Action will mentor a new generation of researchers by providing Early Stage Researchers an opportunity to develop both scientific and management skills. At the same time the Action will actively promote gender balance and women researchers to management positions.
