Nonlinear wide-spectrum fiber-optic light source

Abstract

The application discloses a nonlinear wide spectrum fiber light source, which is a technology for expanding the spectrum of a light source by using the third-order nonlinear effect in an optical fiber. High-power laser with two wavelengths is injected into a high nonlinear optical fiber as pumping light to achieve spectrum conversion and light power transfer, so that a wide spectrum light source and high output power are realized. The width and power of the spectrum of the light source are related to the pumping light power and the parameters of the nonlinear optical fiber. The light source power theoretically has no upper limit. The light source is used for a high-precision fiber interferometer, which is a brand-new technical approach.
