Ultrafast lasers pulses induced ablation of nickel-titanium (NiTi) alloy substrates immersed in deionized water yielded a high-throughput of polycrystalline core - amorphous shell NiTi nanoparticles (NPs) owing to the high pulse energy of femtosecond (fs) ...
Chip-based, single-frequency and low phase-noise integrated photonic laser diodes emitting in the violet (412 nm) and blue (461 nm) regime are demonstrated. The GaN-based edge-emitting laser diodes were coupled to high-quality on-chip micro-resonators for ...
Materials properties are strictly dependent on their microstructure. The internal symmetries and the disposition of the constituting atoms of a material, which depend on its crystallographic structure, greatly affect its response to mechanical, electromagn ...
Bubbles generated with lasers in liquids under confinement have been investigated for their potential use as the driving mechanism for liquid micro-jets in various microfluidic devices, such as needle-free jet injectors. Here, we report on the study of bub ...
In this manuscript, we describe a simple and accurate method for finding the temporal overlap of the laser pump and electron probe pulse in ultrafast TEM. Our approach is based on the observation that the outline of a nanoparticle blurs at time zero, a phe ...
Laser-induced forward transfer (LIFT) technique is an emerging micro additive manufacturing (AM) technique that has been widely used to print a variety of materials. Distinguished from other nozzle-based AM techniques, LIFT operates without the existence o ...
The present invention relates to an electrically tunable photonic resonator device for a component having a fast and flat actuation response, comprising: - At least one optical waveguide with an optical interface for coupling in laser light, - At least one ...
Development of needle-free methods to administer injectable therapeutics has been researched for a few decades. We focused our attention on a laser-based jet injection technique where the liquid-jet actuation mechanism is based on optical cavitation. This ...
Additive manufacturing (AM) is a group of processing technologies which has the potential to revolutionize manufacturing by allowing easy manufacturing of complex shapes and small series. One AM-method which is of high interest for processing of metals is ...
We have developed a robust and universal method to transfer functionalized SU-8 microparts with metallic patterns by laser-induced forward transfer (LIFT) technique. To overcome the difficulty of metal patterning on high-aspect ratio SU-8 microparts on the ...
