Recent development in the field of fibre lasers undoubtedly belongs to
one of the most spectacular achievements of photonic science and
research. New trends lead to a wide variety of systems with various key
performance features ranging from high precision for metrology to
ultrahigh power for cutting and welding with capabilities to provide
watts or even kilowatts (!) of optical power. High energetic efficiency
is the key for green and high power Tm-doped fibre lasers operating at
around 2 μm, which is the main topic of this project, being well in
line with the call. The key of our proposal is increasing Tm-doped fibre
laser efficiency by homogenously embedding rare-earth (RE)-doped
nano-particles into glassy matrices. This needs to address a substantial
issue of nanoparticle’s thermal stability derived from their
composition. The project will focus on methods of preparation of novel
thulium-doped (thulium/holmium-doped) nano-crystalline titanates

with the aim to enhance luminescence of the prepared materials. Such
novel materials and methodological approaches of their fabrication will
represent main results of the project.
