Applications of Nanoparticle-Containing Plasmas for High-Order Harmonic Generation of Laser Radiation

摘要: The use of nanoparticles for efficient conversion the wavelength ultrashort laser toward deep UV spectral range through harmonic generation is an attractive application cluster-containing plasmas. Note that earlier observations HHG in were limited by using exotic gas clusters formed during fast cooling atomic flow from jets 1-4. One can assume difficulties definition structure such and ratio between atoms/ions flow. characterization phase cluster production was currently improved sophisticated techniques (e.g., a control nanoparticle mass spatial distribution, see review 5). In meantime, plasma has demonstrated some advantages over 6. commercially available nanopowders allowed precisely defining sizes these plume. ablation technique made possible predictable manipulation characteristics, which led to creation plumes containing mainly with known structure. latter allows nonlinear optics, X-ray emission clusters, deposition fixed parameters on substrates semiconductor industry, nanostructured nanocomposite films, etc.
