Embodiment Construction

[0012] A high-power and high-brightness laser light source based on fiber optic cone coupling, including a fiber optic cone 103 formed by fusion drawing of several optical fibers 100 and having loose pigtails on the large end side; each fiber 100 of the loose pigtails is connected by a A laser 101 with a collimating lens assembly 102 is connected to the laser.

[0013] During specific implementation, the laser 101 adopts an edge-emitting diode laser, which has the advantages of small volume and high luminous efficiency; the collimator lens combination 102 adopts a single aspherical lens or two cylindrical lenses, which can make the laser The remaining divergence angle reaches the mrad level. The optical fiber 100 is composed of a core made of quartz and a cladding made of quartz; both the core and the cladding are made of quartz material, so that the melting point of the entire optical fiber is consistent, which is conducive to melting and drawing the optical fiber cone, and t...

Abstract

The invention relates to integrated laser sources, in particular to an optical fiber light cone coupling based high-power high-brightness laser source which solves the problem of interaction between output light spot area and optical fiber bundle output power of an existing integrated laser source. The optical fiber light cone coupling based high-power high-brightness laser source comprises an optical fiber light cone which is made by fusion drawing of a plurality of optical fibers, the large end of the optical fiber light cone is provided with scattered pigtail fibers, and each optical fiber of the scattered pigtail fibers is connected with a laser which is provided with a collimating lens combination through a connector. The optical fiber light cone coupling based high-power high-brightness laser source is small in size, convenient, flexible, simple to mount and debug, high in output light power density, small in output light spot area and convenient for coupling with a subsequent optical system, and is widely applicable to the fields of laser illumination, laser processing, display projection systems taking laser as light sources, and the like.

Description

technical field [0001] The invention relates to an integrated laser light source, in particular to a high-power and high-brightness laser light source based on optical fiber light cone coupling. Background technique [0002] With the continuous advancement of science and technology, the demand for laser light sources in various fields is becoming more and more significant, especially the demand for high-power, high-brightness and good beam quality light sources. However, the current laser technology still cannot meet the requirements of high output power due to heat dissipation and other issues. Therefore, it is necessary to find an effective high-power light source integration method to meet the current application requirements for high-power laser light sources. [0003] At present, light source integration mostly adopts beam combining technology, and the typical combining method is incoherent beam combining. Incoherent beam combining technology includes the method of usi...
