The Impact of Femtosecond Laser Wavelength on Plasmonic Gold Nanostructures

In a recent study, the formation of gold nanobumps, nanocones, and nanojets using laser direct writing techniques was investigated using different laser wavelengths. The results showed that the wavelength of the laser used impacts the size and shape of the formed structures, making the laser wavelength an important factor to consider when creating plasmonic nanostructures.

Supercontinuum Laser

A supercontinuum laser is a type of laser that generates a broadband spectrum of light. This spectrum extends over a wide range of wavelengths, from the ultraviolet to the infrared region. The term “supercontinuum” is derived from the fact that the laser’s spectrum is continuous, unlike that of a typical laser, which is typically limited to a narrow range of wavelengths.

Non-Linear Optics

Non-linear optics is a branch of optics that deals the interaction between light and matter, and the ways in which the behavior of light can be altered or controlled through the use of various materials and techniques.
