A team of researchers at the University of Maryland’s Energy Research Facility has set a record for guiding light in 45-meter-long air waveguides.
Researchers from the University of Strathclyde have developed laser-driven ‘plasma mirrors’ that are capable of reflecting or manipulating light.
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.
Laser pointers are a popular tool for presentations, pointing out objects at a distance, and even as a toy for pets. However, it is important to understand the science behind laser pointers before making a purchase.
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.
Holographic optical elements (HOE) are devices that use holography, a process that records and reproduces the interference patterns of light waves, to manipulate and control light.
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.
The field of micro-optics is rapidly growing and essential advancements are being made in multi-photon laser lithography (MPL) for 3D printing. MPL, also known as two-photon or multi-photon polymerization, is a game-changing technology that is attracting increasing industrial interest from key established companies in the field.
