Few-femtosecond resolved imaging of laser-driven nanoplasma expansion
New Journal of Physics, 2022 The free expansion of a planar plasma surface is a fundamental non-equilibrium process relevant for various fields but as-yet experimentally still difficult to capture.

Laser-to-droplet alignment sensitivity relevant for laser-produced plasma sources of extreme ultraviolet light [PDF]
, 2018 We present and experimentally validate a model describing the sensitivity of the tilt angle, expansion and propulsion velocity of a tin micro-droplet irradiated by a 1 {\mu}m Nd:YAG laser pulse to its relative alignment.

Controlled biopolymer roughness induced by plasma and excimer laser treatment
eXPRESS Polymer Letters, 2013 A new method for biopolymer poly-L-lactic-acid (PLLA) surface nanostructuring with surface plasmon resonance appearance is proposed. The motivation of this work is to determine optimal conditions for rough or flat biopolymer surface which may find broad ...
