Lay summary
The IP project is the continuation of the former SNSF project 7 IP 62635 between the Institute of Applied Physics (IAP) of the University of Bern and the General Physics Institute (GPI) of Russian Academy of Sciences.The participating research institutions are the Laser Division of the IAP, the Laser Induced Surface Phenomena Department of Natural Sciences Center of GPI, and the Department of Laser Crystals & Solid-State Lasers of the Laser Materials and Technologies Center of GPI.

The joint research activities between the Laser Division of the IAP and the Laser Induced Surface Phenomena Department of GPI include:
•ultra short pulse laser assisted production of nanostructured materialssuch as nanoparticles, carbon-based nanocomposite coatings, or laser-sintered materials;
•the study of femtosecond laser ablation of diamond materials, includingsingle crystals, polycrystalline diamond plates, and nanocrystalline diamond films.
•femtosecond laser micro- and nanostructuring of diamond materials andsuper hard coatings from diamond-like carbon.
The joint research activities between the Laser Division (IAP) and the Department of Laser Crystals & Solid-State Lasers (GPI) will focus on:
•the development and investigation of high efficient diode pumped thuliumlasers (based on Tm:YVO4, Tm:YALO3 and others crystals) with effective generation of picosecond and femtosecond pulses of two micron spectral range;
•the growth of single-crystal fibers of Nd3+ or Er3+ doped garnet by amethod of "minipedestal with laser heating" and study of fiber laser generation using diode pump and Ti-sapphire laser pump;
•the development technology production of vanadate crystal fiber andinvestigation of diode pumped vanadate fiber lasers;
•the development of the growth technology of mixed vanadatesNd:YxGd1-xVO4 with broad line width;
•the spectroscopy of cerium ions in high efficient scintillating crystalsand glass, as well as the spectroscopy of Nd3+ ions in mixed vanadates.

The realization of the planned activities in the framework of the IP project will result in an improvement of working conditions in Russian laboratories, an improvement of the education of PhD and diploma students to be involved in the project, and an enhancement of professional qualification of the project participants. The strengthening of the collaborative network between Russian and Swiss research institutes, the enhancement of the mobility of the GPI research teams and their competitiveness in the international scientific community will be the primary result of the IP. The extension of joint research areas, motivated by innovative laser technologies and novel laser applications will be of great scientific interest and benefit for both GPI and IAP.
