Invisible laser system and optical path visualization method thereof

Abstract

The invention discloses an invisible laser system and an optical path visualization method thereof and belongs to the technical field of laser. The invisible laser system comprises an invisible laser generator for generating invisible laser; a visible light generator for generating visible light; and an optical path visualization component which is arranged in light paths of the invisible laser and the visible light, and at least comprises a first incoming end, a second incoming end and a first outgoing end, wherein the invisible laser is incident at the first incoming end; the visible light is incident at the second incoming end; and all invisible laser and at least a part of visible light are output in parallel at the first outgoing end. According to the invisible laser system and the optical path visualization method thereof, all invisible laser only exists in the direction parallel to the light path of the visible light, and the invisible laser does not exist in other directions, thereby eliminating radiation risk.

Description

Technical field [0001] The present disclosure relates to the field of laser technology, and in particular to an invisible laser system and a method for visualizing its optical path. 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 Laser (wavelength 10.6μm) invisible lasers are often used to cut glass substrates, repair display panels, cut lines, and make polysilicon active layers. When the laser is installed and poor processing occurs, engineers are required to debug the laser. However, since the laser light emitted by this laser is invisible, this brings inconvenience and radiation risk to engineers when debugging the laser. [0003] figure 1 A schematic diagram of an invisible laser system 100 is shown. The invisible laser 111 emitted by the invisible laser generator 110 passes through the laser adjusting ...

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.
