For more than 500 years, humans have mastered the technology of making glass into lenses to refract light, and then bend or combine these lenses to magnify and clear images at close and long distances

University of Central Florida researchers have developed a new type of laser beam that doesn't follow long-held principles about how light refracts and travels.The findings, which were published r

The figure below shows a schematic diagram of the principle of non-degenerate two-photon absorption (NTA), which is used for the detection of mid-infrared (MIR) by silicon-based cameras. In this detec
