Abstract

A device comprising: - a nonlinear optical fiber (F); - a pumping system; - an optical cavity and an active medium, such as an active optical fiber (Fm), which is located in the optical cavity and passed through by The pump provided by the pumping system is configured and arranged to generate and launch chaotic pulses of laser light into the nonlinear fiber (F) wherein the nonlinear fiber (F) excites a nonlinear effect in order to generate And the supercontinuum light in the form of light pulses randomly distributed with time is emitted from the output end of the nonlinear optical fiber (F). The invention also relates to the various uses of the proposed device for various applications of bright light sources of low price and having a sufficiently broad-band spectrum.

Description

technical field [0001] The present invention relates to broadband light emitting devices comprising nonlinear optical fibers which generate and emit supercontinuum light when their nonlinear effects are excited by laser pulses, and more particularly to devices wherein said Laser pulses are chaotic in nature, and the device emits supercontinuum light in the form of light pulses randomly distributed over time. [0002] The invention also relates to a series of uses of the proposed device for various applications. Background technique [0003] Several broadband supercontinuum light emitting devices are known in the prior art, some of which will be mentioned below. [0004] Commercially available supercontinuum sources are based on picosecond lasers operating according to a phase-synchronous mechanism of laser cavity modes, often referred to as "mode-locked", which excite nonlinear photonic crystal fibers. Mode-locked laser technology is expensive, so the cost of a supercontin...
