Novel methods for production of nanomaterials are urgently needed for various applications, especially in defence. In this work, we propose a direct method to produce silver nanoneedles using the femtosecond laser direct writing (LDW) technique. Femtoseco... see more

Water wetting of a structured multi-layered thin film consisting of bottom silver and top polymer layers microstructured by femtosecond laser pulses was studied. The periodic trenches were ablatively produced on the top polymer layer of the film using 515... see more

Electrospun mats from nano/micro-fibers with control porosity and pore shape may be ideal candidate for tissue engineering scaffolds. In this study three type of poly(vinyl alcohol) (PVA) mats of 48-65 µm thickness with different nano/micro-fibers di... see more

Multi-photon polymerization by interference is a promising technique for mass fabrication of 3D periodic micro-structures over large areas, which can be used in various fields such as biomedicine (cell growing), photonics (photonics crystals), etc. As dir... see more

A femtosecond laser can be used for single or multiple writing processes to create sub 10-µm lines or holes directly without the use of masks. In this study, we characterized the depth and width of micro-channels created by femtosecond laser micro-scribin... see more

Femtosecond laser surface micro-texturing has emerged as a promising technology to enhance the tribological properties of different kinds of electromechanical devices. In this research paper, we have exploited the intrinsic flexibility and micrometric acc... see more

This paper employs Bayesian probability theory for analyzing data generated in femtosecond pump-probe photoelectron-photoion coincidence (PEPICO) experiments. These experiments allow investigating ultrafast dynamical processes in photoexcited molecules. B... see more

Purpose: Determine the benefits and challenges of combined femtosecond laser-assisted cataract surgery with the Catalys® system (Abbott, Abbott Park, IL) and vitrectomy.Design: Retrospective studyMethods: We retrospectively reviewed eight consecutive case... see more

We report on a Chirped Pulse Amplification (CPA)-based Titanium:Sapphire (Ti:Al2O3 or Ti:Sapphire) amplifier that uses a single grating stretcher and compressor configuration. The 8-pass amplifier configuration is able to yield 70 µJ pulse energy at 10 Hz... see more
