Abstract
An invisible laser system and an optical path visualization method thereof are disclosed. 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 optical paths of the invisible and visible light, and comprising a first and second incident end and a first outgoing end. The invisible laser light is incident on the first incident end, and the visible light is incident on the second incident end. 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. All of the invisible laser light is present in a direction parallel with the optical path of the visible light, and no invisible laser light is present in other directions, so radiation risks are eliminated.
