A world record power 2.5kW laser providing from picosecond down to femtoseconds pulses at repetition rates up to 1GHz with excellent beam quality will be developed and brought to the market at highly competitive costs enabling widespread industrial uptake.
The project proposes a new concept of label-free, multi-modal microscopy and endoscopic imaging operating in this new wavelength region with multiple imaging and spectroscopic technologies, including NIR confocal reflectance microscopy, multi-photon microscopy and spontaneous Raman spectroscopy.

This is an ambitious frontier research project aimed to build a challenging all-fiber high-power ultrafast laser system operating at 980 nm. There is no such laser available on the market. The great challenge is attributed to the competitive luminescence at 1030 nm in Yb-doped active fiber. However, the short-pulsed lasers operated at 980 nm are in high demand nowadays due to the almost unique opportunity to obtain 490 nm pulse operation by efficient frequency doubling for replacement of costly and inefficient argon lasers. The argon laser has been widely used for non-invasive medicine and power therapy. The future development of these applications is limited by the output parameters of the argon laser. Additionally, the pulsed high-power laser operated at 980 nm would be attractive as a pump source for upconversion nanoparticles integrated into the microstructured fibers. These nanoparticles absorb 980 nm light and illuminate in the visible wavelength range. The pumping of nanoparticles embedded in highly nonlinear fiber by a short intense pulse source would provide a platform for novel nonlinear effects. Within the frame of the project, the ultrashort pulse high power laser operated at 980 nm wavelength will be realized and implemented for frequency doubling and nonlinear pumping of upconversion nanoparticles.
The new initiative is aimed to revolutionize laser-driven material processing and bring technology beyond the current limits and precisions standards. The state-of-the-art ultrafast fiber laser delivering femtosecond pulses in GHz repetition rate with tens to hundreds of microjoule-level pulses will be developed within the frame of this project. The laser system will enable to process materials without thermal damage engaging in nonlinear absorption processes, which nature is not well defined so far. Within the scope of the research, we will discover the nonlinear processes and mechanisms of material responses under ultrashort pulses processing with a high repetition rate and high energy. We aim to enable material processing of the hard and soft materials with a few micrometers accuracy and cracks-free quality at a speed one thousand times faster than the existing record
