The term is also used to describe a beam of light that has such a zero in it. The study of these phenomena is known as singular optics. dave chisnall walk on music

"WebNov 26, 2024 · Fiber lasers use an optical fiber cable made of silica glass to guide light. The resulting laser beam is more precise than with other types of lasers because it is straighter and smaller. They also have a small footprint, good electrical efficiency, low maintenance and low operating costs. " - Optic beams
