The mechanical effects associated with the collapse of laser-induced cavitation bubbles are central to numerous medical and industrial applications, particularly where precise, localized energy delivery is required. This study examines the interaction of nanosecond-pulsed infrared laser ... Mehr lesen
Laser-Heated Pedestal Growth (LHPG) is a crystal growth technique that employs a focused laser beam to melt a source material, creating a molten zone that is precisely controlled to produce high-quality single crystals. This method is particularly advantageous for growing crystals with ... Mehr lesen
High average power lasers are currently being designed for laser fusion applications. Single beamlines with laser amplifiers should be able to deliver up to 10 kW average power at 10-Hz repetition rate. For achieving a 5 to 10 % wall-plug efficiency, this means that at least, 50 kW will ... Mehr lesen
The modelling of the optical and thermal response of translucent composite materials submitted to a high-energy laser irradiation is very complex, as glass fibers-reinforced polymers are highly heat-sensitive and their physical behavior dramatically changes at high temperatures. All ... Mehr lesen
The use of lasers to fragment and remove kidney stones (Laser Lithotripsy) has become increasingly popular in surgical procedure due to its high success rate and minimal complications. However, the precise mechanisms behind the stone fragmentation process are not yet fully understood. ... Mehr lesen
Materials such as aluminium with high thermal and electrical conductivities are of industrial interest, particularly for the automotive industry in the current context of increasing production of electric vehicles. The reflective properties of this material make it difficult to process ... Mehr lesen
Laser powder bed fusion (LPBF) is one of the most beneficial manufacturing methods for its precision and ability to create parts with complex geometry, although high thermal gradient due to the considerable temperature difference between ambient and peak temperature appeared during laser ...

Laser cutting process is usually employed in machining process, however it is also applied for dismantling nuclear facilities. Contrary to mechanical processes where tools wear out quickly and are often renewed, laser cutting process is a contactless approach, therefore there is no ... Mehr lesen
Micro-lenses with potential applications in optics on the surface of the various heavy-metal oxide glasses were created and studied experimentally [1-2]. Laser direct writing using continuous-wave laser emitting at 447 nm was successfully performed [2]. The aim of this study is to ... Mehr lesen
High power lasers have a wide range of applications. The goal of this work is to analyze and further optimize a beam expander made of 2 lenses used with a kW class laser. The preliminary lens design is performed using an optical design software but its performance analysis, when used ... Mehr lesen
