An 800 nanometer, 50 femtosecond, 0.75 Watt, pulsed Ti:Sapphire laser system was usedas the source infrared beam. A beam expander was used to expand the beam to a diameter of approximately 6.5 mm, and the beamwas focused through a 25 mm focal length achromatic lens to produce laser-induced plasma in ambient air. A 40 kHz ultrasonictransducer was used to detect the plasma. A second harmonic generation crystal was placed within the beam expander to generate400 nm blue light, enabling production of THz in the plasma via four wave mixing; a third-order nonlinear process. Whileplasma-produced THz was not detected, all the preliminary groundwork was accomplished, including full characterization of theplasma, blue light, and alignment of the system to generate and detect THz. The electro-optic detection apparatus was assembled,aligned and used to successfully detect a diagnostic THz signal.\u003c\/p\u003e","brand":"Mia Karts","offers":[{"title":"Default Title","offer_id":51968884310304,"sku":"NEW1288308663","price":19.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0980\/7426\/3840\/files\/711W4drkBRL.jpg?v=1783716676","url":"https:\/\/miakarts.com\/products\/production-and-characterization-of-femtosecond-laser-induced-air-plasma-1288308663","provider":"Miakarts Books","version":"1.0","type":"link"}
