Supercontinuum generation is a process in which a short pulse of light, typically from a laser, is transformed into a broad spectrum of colors. This occurs when the light pulse travels through a nonlinear medium, such as a special type of optical fiber. The interaction between the light and the medium causes the pulse to spread out, creating a continuous range of wavelengths. This phenomenon is useful in various applications, including spectroscopy and telecommunications. The wide spectrum produced allows for precise measurements and improved data transmission, making supercontinuum sources valuable tools in both scientific research and industry.
