(Phys.org)—A team of researchers with affiliations to several facilities in Japan has succeeded in developing an atomic laser that operates at the shortest wavelength yet. In their paper published in ...

Eye injuries are of primary concern. The effect to the eye depends on various factors, including pupil size, pigmentation, laser pulse duration and repetition, and wavelength. Pierre Gougelman had the ...

Wavelength division multiplexing (WDM) is currently used extensively in optical fibre networks to enhance the carrier capacity of optical fibres where each wavelength in a multiwavelength bunch is ...

The devices and tools used in medicine are becoming smaller. They have greater functionality and are expected to last longer than earlier devices. Design, manufacturing, and packaging the devices and ...

Small lasers have dimensions or modes sizes close to or smaller than the wavelength of emitted light. In recent years there has been significant progress towards reducing the size and improving the ...

Physicists have discovered how to fix a major problem that occurs in lasers made from a new type of material called quantum dots. The never-before-seen phenomenon will be important for an emerging ...

Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and Vienna University of Technology (TU Wien) have invented a new type of tunable semiconductor laser that ...

NeoClear is a two-step laser treatment that targets acne. "The Neoclear laser, a type of Nd- laser, is effective for treating ...

An excimer laser's high-power ultraviolet emission enables applications in research, micromanufacturing and biomedicine. Rainer Paetzel and Ruediger Hack provide an introduction to the technology and ...

Researchers have created visible lasers of very pure colors from near-ultraviolet to near-infrared that fit on a fingertip. The colors of the lasers can be precisely tuned and extremely fast -- up to ...

Pierre Gougelman had the first glass eye factory in the United States in 1851. At first, the public thought artificial eyes actually gave their wearers new sight. If only glass eyes worked that way!
