Ongoing Projects
SMART: Development and investigation of novel optical parametric generators: towards subnanosecond pulses
Number: 01.2.2-LMT-K-718-03-0004
Head: Dr. J. Vengelis (VU, Lithuania)
Participants: -
Duration: 36 months
Funding: 698 987,42 EUR
Funding agency: The Research Council of Lithuania
Project description:
The aim of this project is to develop commercialization ready optical parametric generator technologies for generation of subnanosecond pulses in the VIS and NIR spectral range based on the nonlinear optics methods. Comprehensive research of optical parametric generation in the VIS and NIR spectral ranges when pumping with subnanosecond pulses is planned: various OPG configurations in different nonlinear crystals will be tested; experimental and theoretical investigation of generation dynamics will be carried out; OPG output parameters (pulse energy, duration and frequency tuning range) will be optimized; measurement of the laser-induced damage threshold (LIDT) in various nonlinear crystals and their coatings will be performed in order to determine optimal OPG configuration with respect to LIDT and parametric generation threshold and corresponding technological solutions for realization of the OPG. Finally, a prototype of subnanosecond OPG will be developed.
High repetition rate femtosecond filamentation- induced laser-matter interactions in transparent solids (FEMTOLAMA)
Number: S-MIP-22-40
Head: Prof. A. Dubietis (VU, Lithuania)
Participants: -
Duration: 24 months
Funding: 145 844 EUR
Funding agency: The Research Council of Lithuania
Project description:
The main objective of the Project is investigation of accumulation effects that lead to optical degradation and damage induced by high repetition rate femtosecond filamentation in transparent solids over a wide spectral range. Since most of these effects are detrimental to both, characteristics of the broadband ultrashort-pulsed light (supercontinuum) and optical properties of the material itself due to evolving multipulse optical damage, the special emphasis will be given to find optimal operating conditions, where these effects could be eliminated, or at least suppressed to a large extent.
Development of high repetition rate tunable wavelength UV-VIS femtosecond laser system. (HIREPUVIS)
Number: -
Head: Dr. J. Vengelis (VU, Lithuania)
Participants: -
Duration: 36 months
Funding: 150 000 EUR
Funding agency: The Research Council of Lithuania
Project description:
The aim of this project is to develop watt-level average power high repetition rate broadly tunable wavelength UV-VIS femtosecond laser system. This will be accomplished by developing a combined laser setup consisting of laser amplifier, harmonic generator and synchronously pumped optical parametric oscillator. Such combined laser system will superceed capabilities of any currently existing laser or optical parametric generator system used for spectroscopy, nonlinear microscopy, material science and laser micromaching applications in terms of measurement / micromachining speed, versatility, accuracy and efficiency.
