Reference number : GC-2017-Q3-00670, amendment number : , agreement type : G, recipient legal name : Kieffer, Jean-Claude (Institut national de la recherche scientifique), recipient country : CA, recipient province : nan, recipient city : Quebec|Québec, recipient postal code : nan, program name english : Idea to Innovation, program name french : De l'idée à l'innovation, program purpose english : The present proposal concerns a market assessment related to the development of a source of frequency agile_x000D_
radiation (from UV to THz) obtained by using multi-color filamentation in an in-line setup and by spectrally_x000D_
shaping a femtosecond laser beam. High power frequency agile sources of optical radiation (from the visible to_x000D_
the THz) are not technologically mature due to complexity and cost. The current approach in non-linear optical_x000D_
interaction and generation of radiation at some controlled distance is based on splitting a laser beam in several_x000D_
beams, changing the frequency of some of these beams and recombining the various beams. Precise alignment,_x000D_
system complexity and high stability of the multi-beam system are critical and difficult to control, which limits_x000D_
the practical use in a real environment. We developed a novel approach which circumvents the current_x000D_
limitations offering a way to spatially and temporally overlap two-color pulses or multi color pulses in a_x000D_
completely collinear geometry for the generation at long distance of tunable UV, VIS, IR and/or THz source_x000D_
via nonlinear optical interaction or photocurrent generation processes. The system developed and tested allows_x000D_
an easy generation of frequency-agile radiation through programmable control of the laser spectral amplitude_x000D_
and phase. The optical source can be generated on a range of distances (100m - km) from a single laser beam_x000D_
modulated into collinear multi-pulses of different wavelengths, with a controlled temporal delay between the_x000D_
pulses, which are combined at a controlled distance in a multiple-color filament. The system ensures a_x000D_
complete insensibility to alignments, vibrations and turbulences on long distances propagation particularly in_x000D_
air. The number of optical components in the present device is reduced offering a robust and compact way to_x000D_
generate remote radiation with perfectly controlled parameters for remote sensing or spectroscopy. The stable_x000D_
and programmable generation of tunable Infra-red emission in the range between 2µm and 12µm and THz_x000D_
radiation in the 2THz to 6THz range has been demonstrated at long distances., program purpose french : The present proposal concerns a market assessment related to the development of a source of frequency agile_x000D_
