Abstract

The invention discloses a low-radiation portable laser. The laser includes a laser body, the laser body is sleeved by an anti-radiation protection cover, an outer wall of one side of the anti-radiation protection cover is provided with external threads, one side of the laser body which is close to the external threads is provided with a dustproof cover, one side of the dustproof cover which is close to the laser body is provided with a thread groove, the thread groove is matched with the external threads, barite chips are adhered to an inner wall of one side of the anti-radiation protection cover which is away from the dustproof cover, an optical filter is embedded between inner walls of the anti-radiation protection cover, an electromagnetic shielding film is attached to one side of the optical filter which is away from the laser body, the optical filter is located at one side the laser body which is away from the dustproof cover, two sides of the anti-radiation protection cover which are close to the optical filter are provided with positioning holes, and outer sides of the positioning holes are provided with positioning rods. The low-radiation portable laser provided by the invention is reasonable in design and convenient to carry, the generated radiation is low, and the use quality and the life of the laser are effectively improved.

Description

technical field [0001] The invention relates to the technical field of lasers, in particular to a low-radiation portable laser. Background technique [0002] According to the working medium, lasers can be divided into four categories: gas lasers, solid-state lasers, semiconductor lasers and dye lasers. Recently, free electron lasers have also been developed, and high-power lasers are usually pulsed output. A laser is a device that uses the principle of stimulated radiation to amplify or oscillate light in certain excited substances. It uses light, electricity and other methods to stimulate the substance, so that some of the particles are excited to a higher energy state. When this When the number of particles in this state is greater than the number of particles in a lower energy state, due to stimulated radiation, the substance can amplify the light radiation of a certain wavelength, that is, when the light radiation of this wavelength passes through the substance, the emis...
