Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0018] Such as figure 1 As shown, the embodiment of the present invention relates to a fiber laser, including: an ultrashort pulse fiber pump source and a visible light enhanced photonic crystal fiber, wherein the ultrashort pulse fiber pump source and the visible light enhanced photonic crystal fiber are directly connected to each other. It is connected by fusion splicing, and the central wavelength of the output laser of the ultrashort pulse fiber pump source is consistent with the zero dispersion point (zero dispersion wavelength) of the optical fiber of the visible light enhanced photonic crystal.

[0019] The ultrashort pulse fiber pump source is used to output ultrashort pulse laser as ...

Abstract

The invention discloses a fiber laser. The fiber laser comprises an ultrashort pulse fiber pumping source and a visible light enhanced pohotonic crystal fiber, wherein the ultrashort pulse fiber pumping source and the visible light enhanced pohotonic crystal fiber are connected by adopting a direct welding manner; and the central wavelength of the laser output by the ultrashort pulse fiber pumping source is consistent with the fiber zero dispersion point of the visible light enhanced pohotonic crystal fiber. The minimum wavelength of a spectral region output by the fiber laser is less than or equal to 0.4 micron and the maximum wavelength is greater than or equal to 1.1 micron, so that the working range of a visible light photoelectric detector can be completely covered so as to effectively interfere the visible light photoelectric detector.

Description

technical field [0001] The invention relates to the technical field of lasers, in particular to an all-fiber wide-spectrum fiber laser. Background technique [0002] Broad-spectrum laser means that when a very high-intensity ultrashort optical pulse passes through a nonlinear medium, due to the joint action of the nonlinear effect in the optical medium and the dispersion effect of the optical fiber, many new frequency components are generated in the outgoing spectrum, and the spectrum is obtained. Extremely broadened laser pulses. [0003] Broad-spectrum lasers have a wide-spectrum output in the frequency domain that extends continuously from visible light to infrared and even ultraviolet regions, covering a spectral range of thousands of nanometers. This feature can make it a very effective white light source for various applications such as detection, scanning, detection and interference. [0004] Visible light photodetectors usually work in the range of 0.4 to 1.1 micro...
