Laser ablation is a process that uses high-energy laser pulses to precisely remove or vaporize materials from a solid surface. When the laser beam focuses on the target material, it absorbs the laser ...

When laser energy is deposited in a target, numerous complex processes take place too rapidly to observe visually. To study and adapt such processes, researchers often use computer modeling. However, ...

Gigahertz femtosecond lasers are suited to enhance and regulate laser machining quality to engineer the physicochemical properties of materials. Materials scientists seek to understand the ...

Ultra-uniform nanogratings of sub-50-nm periods and near-10-nm groove widths on HOPG can be stably and efficiently fabricated by high-NA focused femtosecond laser irradiation under water immersion.

The laser wavelength, pulse duration, and fluence (energy density) significantly influence the ablation process and the resulting plasma plume. Shorter wavelengths and higher fluences generally lead ...

The 445 nm semiconductor laser technique offers a breakthrough in cholesteatoma treatment, ensuring effective tissue removal ...
