Abstract

The invention discloses an optical gate with a safety monitoring function for a time-sharing optical fiber laser. The optical gate comprises a laser transmission fiber, an input port, a collimating mirror, a first reflector, a second mirror, a light receiver, a first focus lens, a second focus lens, a first output port, a second output port, a first output optical fiber, a second output optical fiber, an integrated circuit board, a liquid crystal display screen, a first electrode plate, a second electrode plate, a third electrode plate, a first temperature control switch, a second temperaturecontrol switch, a third temperature control switch, a fourth temperature control switch, a first proximity switch, a second proximity switch, a third proximity switch, a fourth proximity switch, a first photoelectric detector and a second photoelectric detector, which are mounted on an optical gate. Internal light paths of the optical shutter are switched according to requirements, laser is controlled to be coupled into different optical fibers for transmission, light sources are provided for multiple workstations within different time, the working efficiency is improved, meanwhile, a series of detectors are adopted for monitoring the internal state of the optical shutter, and safe use of the laser is guaranteed.

Description

technical field [0001] The invention belongs to the field of optical fiber lasers, and in particular relates to a time-sharing optical shutter for optical fiber lasers with a safety monitoring function. Background technique [0002] Laser is known as "the fastest knife, the most accurate ruler, and the brightest light", and it has been widely used in industry, military, medical and other fields. In the industrial field, with the continuous development of laser technology, laser processing gradually replaces traditional industrial manufacturing methods, such as cutting, welding, cladding, etc., and has the characteristics of high production efficiency, more processing materials, high precision, and flexible operation. Fiber laser uses glass fiber doped with rare earth elements as the gain medium. It has the advantages of good beam quality, high conversion efficiency, good heat dissipation and high reliability. It is one of the mainstream light sources for laser processing. A...
