This November, two HiLASIANS joined the ranks of doctoral alumni of Charles University and Czech Technical University in Prague.
Member of Scientific Laser Applications (SLA), Jan Hrabovský, successfully defended his PhD thesis titled “Rare-earth doped and undoped solid-state materials for photonic applications” under the supervision of Dr. Martin Veis, Faculty of Mathematics and Physics of the Charles University.
He devoted his thesis to investigating the structural, optical, and magneto-optical properties of undoped and rare-earth doped solid-state materials for photonic applications, focusing on both amorphous and crystalline systems. A new rapid and precise method for mapping rare-earth ion distribution in luminescent materials was proposed. He also presented a novel Combinatorial Judd-Ofelt analysis to optimize the spectroscopic characterization of rare-earth-doped materials with an interactive online tool (www.loms.cz).
A designer from the Engineering and Technical Support (ETS) department, Tomáš Tichý, successfully defended his PhD thesis titled “Finite element analysis of electromagnetic and temperature fields in engineering application” under the supervision of Dr. Jan Zemen from the Faculty of Electrical Engineering, Czech Technical University in Prague.
His dissertation focuses on the computation of electromagnetic and temperature fields using FEM in nonlinear electrodynamic and thermal systems. Three case studies were presented: a model of a linear rail accelerator, a model of a magnetocumulative generator, and a model of extruder of 3D printer head.
For the linear accelerator, he proposed a methodology for determining friction force using measured and simulated time-domain waveforms. In case of the magnetocumulative generator, a finite element model was used to describe axial and radial field compression in the microsecond time scale. The last model detailed the thermal history of the material during printing and cooling on substrate, with a focus on subsequent evaluation of the crystalline phase in the polymer.
Big congratulations to Jan Hrabovský and Tomáš Tichý for successfully concluding their studies. We look forward to your future successes!
