Laser-induced ablation dynamics and nigh

چکیده
We investigated the ejection dynamics oftriazene polymer layers in the thickness range of 40 nm to 600 nm upon nanosecond laser ablation at a wavelength of 532 nm. The ablation is due to laser-induced thermal degradation of a small part of the polymer in contact with the silicon substrate. The subsequent dynamics of the flyin polymer layer are measured with sub-nanosecond time resolution. The evaluation ofthe initial velocity for different fil thicknesses gives insight into the energy transfer process during the acceleration of the films

متن کاملDiagnostics of particle dynamics during optically functional thin-film deposition by laser ablation
We describe the diagnostics of the particle dynamics during nanoparticle formation by pulsed laser ablation in a background gas. First, we describe the deposition of ZnO nano-structured thin films, along with the results of Rayleigh scattering observation of ZnO nanoparticle formation in the ablation plume. Then, we propose a new imaging technique, called re-decomposition laser-induced fluoresc...
