Laser optical fiber adjustment device based on optical fiber coupler and optical fiber collimator

Abstract

The invention discloses a laser optical fiber adjustment device based on an optical fiber coupler and an optical fiber collimator and belongs to the precision optical instrument technical field. The laser optical fiber adjustment device comprises an optical fiber coupling system, a transmission system and an optical fiber alignment system; the optical fiber coupling system comprises a laser (1), a optical fiber coupling device (2) and a base (3); the transmission system comprises an optical fiber jumper (4); and the optical fiber alignment system comprises a fiber collimating device (5) and a bottom plate (6). According to the laser optical fiber adjustment device of the present invention, with a laser beam emitted from the laser used as references, the optical fiber coupler is adopted to complete the spatial adjustment of the laser fiber of the laser, and therefore, the low-loss transmission of the laser beam can be realized; and the transmitted laser beam is collimated and sent out by the optical fiber collimator, so that the collimated laser beam can be adopted as the working light source of a precision optical instrument.

Description

technical field [0001] The invention relates to an optical fiber adjustment device, in particular to a laser fiber adjustment device based on an optical fiber coupling / collimator, and belongs to the technical field of precision optical instruments. Background technique [0002] Precision optical instruments are widely used in many fields such as precision test and measurement, equipment detection and analysis, and their working light sources are often provided by lasers through optical fibers. During use, in order to ensure low-loss transmission of the laser beam, it is particularly important to adjust the spatial position of the fiber head. [0003] At present, there are two main ways to adjust the laser fiber: one is to fix the fiber coupling / collimator as a reference and adjust the spatial position of the laser light source; the other is to fix the laser light source as a reference and adjust the fiber coupling / collimator spatial location. However, the laser light sourc...

Problems solved by technology

[0004] In the prior art, the adjustment of the laser fiber is often limited to the independent adjustment of the horizontal X and Y directions, and the precision is not high; and the angle of the Z direction of the laser fiber is not adjusted at the same time, which seriously affects the transmission quality of the laser beam
