Invisible laser system and its optical path visualization method

Abstract

This disclosure provides an invisible laser system and an optical path visualization method thereof, and belongs to the field of laser techniques. According to this disclosure, the invisible laser system comprises: an invisible laser light generator for generating invisible laser light; a visible light generator for generating visible light; and an optical path visualization component arranged in the optical paths of the invisible laser light and the visible light, which at least comprises a first incident end, a second incident end and a first outgoing end, wherein the invisible laser light is incident on the first incident end, and the visible light is incident on the second incident end, and all of the invisible laser light and at least part of the visible light are emitted in parallel with each other at the first outgoing end. According to this disclosure, all of the invisible laser light is only present in a direction parallel with the optical path of the visible light, and no invisible laser light is present in other directions, so the radiation risks are eliminated.

Description

technical field [0001] The present disclosure relates to the field of laser technology, in particular to an invisible laser system and an optical path visualization method thereof. Background technique [0002] Invisible lasers are widely used in device processing and other fields. For example, in the liquid crystal display (LCD) manufacturing process, such as Nd:YAG laser (wavelength 1.064μm), CO 2 Invisible lasers (wavelength 10.6 μm) are often used to cut glass substrates, repair display panels, cut lines, and make polysilicon active layers. During the installation of the laser and the occurrence of poor processing, engineers are required to debug the laser. However, since the laser light emitted by this laser is invisible, it brings inconvenience and radiation risks to engineers when debugging the laser. [0003] figure 1 A schematic diagram of an invisible laser system 100 is shown. The invisible laser light 111 emitted by the invisible laser generator 110 passes t...

Problems solved by technology

However, this infrared observer can only observe a certain point of the optical path and cannot see and debug the entire optical path. The debugging process is very time-consuming, and the risk of radiation is relatively high.
