Modern electronics facilitate the need for fast, efficient, and reliable methods for direct laser-based surface engineering of conductive thin film materials on flexible substrates. Recent advances in pulsed laser source development only incrementally increased the processing speeds, as those are li ...

bursts of pulses;ultra-short laser processing;surface effects;ablation efficiency;
Laser operation in bursts of pulses has recently attracted a lot of attention, as high average powers and pulse energies have become available. Bursts of pulses have become a mean to achieve different laser-matter interaction regimes with a single laser source. We have used an ultra-short pulse lase ...

cavitation bubbles;laser breakdown;tissue phantom;sonoporation;
Precise excitation of cavitation is a promising mechanism for microsurgery procedures and targeted drug delivery enhancement. The underlying phenomenon of interest, jetting behaviour of oscillating cavitation bubbles, occurs due to near-surface interactions between the boundary, liquid, and bubble. ...

The nucleation and growth of cavitation bubbles few micrometers in size in water generated by a 60 ps 515 nm fiber laser is observed and visualized near nucleation threshold. The study is performed by monitoring the plasma size, the cavitation bubble size and the emitted shock waves. The latter two ...

Zaradi prehitrega potovanja taline ob tlačnem litju, se na odlitku pojavi defekt imenovan dvoplastnost. Za upočasnitev hitrosti potovanja taline bi gravure hrapavljali oziroma naredili hrapave. S primerjavo različnih metod hrapavljenja sem izbral obdelavo z laserskim žarkom, ki se je izkazala za naj ...

Delo predstavlja pojav prosto plavajočih nanomehurčkov. Za generiranje nanomehurčkov je bila izbrana metoda presvetlitve vode s kolimiranim laserskim snopom. Opazovanje je bilo osnovano na uporabi podtlačnega udarnega vala, ki je nanomehurčke razširil do velikosti primerne za opazovanje. Meritve so ...
