Invited

The talk reviews our recent advances in fiber based ultrafast mid-IR lasers and frequency combs starting at 2.1 microns and extending beyond 6 microns, with peak powers up to GW level. The more and more demanding requirements set by the modern industrial applications such as fine material processing call for controlling the light generation to its extremes. In case of fine processing of semiconductors understanding and careful analysis of the nonlinear optical phenomena in its complexity allowed finding an optimum laser wavelength as well as optimum set of laser parameters, enabling for the first time 3D structures and stealth dicing of silicon with sub-wavelength spatial resolution. The same type of ultrashort-pulsed sources allows obtaining highly efficient (~50%) internally coherent sub-three cycle frequency combs in 3-6 micron range, opening the way to even longer wavelength combs and new industrial and bio-medical applications.Authors: Irina Sorokina, Norges Teknisk Naturvitenskapelige Univ
