Project: INTEGRA - High average power multi-beam pumped femtosecond optical parametric amplifier
Duration of the project: from 2009-04-01 to 2011-12-01
Description:
Project „High average power multi-beam pumped femtosecond optical parametric amplifier (INTEGRA)“ funded by Lithuanian State Science and Studies Foundation under the Program for the Development of High Technologies
The main goal of this project is the development and optimization of multi-beam pumping system for optical parametric amplifier of broadband pulses using high average power lasers. This goal will be pursued by performing research in four directions: a) development of optical parametric amplifier pumping system comprising of few parallel laser amplifiers (this will allow to combine separate pump beams to amplify parametrically a single broadband signal via multi-beam phase-matching), b) self-diffraction suppression in multi-beam pumped picosecond optical parametric amplifiers, c) multi-beam pumped optical parametric chirped pulse amplification of 10 femtosecond pulses, d) development of multi-beam pumped optical parametric chirped pulse amplifiers prototype. The specific tasks that will be accomplished during the project are: optimal spatial distribution of pump beams, minimization of the impact of self-diffraction on energy efficiency of optical parametric amplification process, optimization of multi-beam pumped optical parametric chirped pulse amplifier. Using the multi-beam pumping of optical parametric amplifiers and diode-pumped laser amplifiers, a 1 kHz system will be developed producing 10-20 fs pulses.
