Description

Technical Field

[0001] The invention relates to the technical field of coupling detection, in particular to a laser beam coupling detection and debugging structure. Background Art

[0002] Laser beam coupling refers to the process of efficiently directing a laser beam into an optical fiber. This process ensures that multiple beams are converged into one without losing beam energy by precisely adjusting the direction and position of the laser beam, thereby achieving higher power and narrower beam width. This technology is widely used in fields such as optical fiber communications, laser processing, and scientific experiments. This process requires not only high coupling efficiency, but also the quality and stability of the laser beam. With the development of optical fiber technology, the core diameter of the optical fiber is required to be thinner and thinner, which requires higher and higher coupling accuracy. By detecting and debugging the structure, the qualified rate of the relative position between the coupling mirror and the optical fiber can be improved, thereby improving the coupling efficiency of the laser beam to the optical fiber. Here, the present invention proposes a laser beam coupling detection and debugging structure.

[0003] According to the search, the Chinese patent document, announcement number: CN210894826U, discloses a rotating mirror frame suitable for coupling multiple pulsed laser beams. The servo motor drives the rotating mirror plate to rotate at a constant speed. When the position mark reaches the position of the position detector, the optical signal emitted by the position detector composed of optical coupling devices is reflected by the position mark. After the position detector receives the optical signal reflected by the position mark, it triggers the laser cavity to output a pulsed laser beam in real time. At this time, the normal of the through hole is exactly at a 45° angle with the optical axis of the system. The pulsed laser beam directly overlaps on the optical axis of the system through the through hole and is output through the output mirror. However, the device cannot accurately and effectively adjust the height and angle of parts such as reflectors during actual use, and there will be manual errors when the device as a whole is installed and positioned, which is more troublesome to adjust, reducing the overall practicality.
