A.a. Serafetinides – 1st expert on this subject based on the ideXlab platform

  • XeCl laser ablation of biocompatible PTFE studied by photothermal beam deflection.
    Lasers in Medical Science, 1997
    Co-Authors: Constantine Skordoulis, Mersini I. Makropoulou, A. L. Bolovinos, A.a. Serafetinides

    Abstract:

    Laser beam deflection is a useful tool for studying the dynamics of the pulsed laser ablation mechanism, and has the advantage of being used as an in situ laser damage monitoring technique for both bulk and thin film polymeric and biological tissue samples. This work employs the photothermal deflection technique to study possible photo-Acoustic Phenomena during the excimer laser ablation of biocompatible polytetrafluoroethylene (PTFE) and to examine the crater surface quality by video microscopy.

  • XeCl laser ablation of biocompatible PTFE studied by photothermal beam deflection

    Abstract:

    Laser beam deflection is a useful tool for studying the dynamics of the pulsed laser ablation mechanism, and has the advantage of being used as an in situ laser damage monitoring technique for both bulk and thin film polymeric and biological tissue samples. This work employs the photothermal deflection technique to study possible photo-Acoustic Phenomena during the excimer laser ablation of biocompatible polytetrafluoroethylene (PTFE) and to examine the crater surface quality by video microscopy. Although photo-Acoustic Phenomena are detected in the laser fluence threshold region, ablation is mainly the result of the photothermal process.

  • experimental study of plate angle effects on Acoustic Phenomena from a supersonic jet impinging on an inclined flat plate
    Journal of the Acoustical Society of America, 2017
    Co-Authors: Masahito Akamine, Susumu Teramoto, Koji Okamoto, Seiji Tsutsumi

    Abstract:

    Acoustic waves from a rocket exhaust jet cause the intense Acoustic loading. Because the exhaust jet impinges on a flame deflector at liftoff of a launch vehicle, an adequate understanding of the Acoustic Phenomena from a supersonic impinging jet is required for prediction and reduction of the level of the Acoustic loading. The previous numerical studies on a supersonic jet impinging on an inclined flat plate [e.g., Tsutsumi et al. AIAA 2014-0882; Nonomura et al. AIAA J. 54(3), 816-827 (2016)] suggested that the plate angle has a large impact on the characteristics of the Acoustic waves from the impingement region. In the present study, experiments were carried out to discuss the effect of the plate angle on this Acoustic phenomenon. By applying the Acoustic-triggered conditional sampling to the schlieren visualization movies, which was proposed by the authors [AIAA 2016-2930], the Phenomena around the impingement region were observed in detail. The results revealed that the plate-angle variation leads to…
