The invention discloses a small folding cavity human eye safety laser which comprises a laser rod (11), a light condensation cavity (12), a xenon lamp (9) and a body (6), the body (6) is of a foldablestructure and comprises a first folding part and a second folding part, a first channel is formed in the first folding part, and a second channel is formed in the second folding part; the laser rod (11) and the light condensation cavity (12) are fixed in the second channel; and the light condensation cavity (12) and the laser rod (11) are arranged in parallel, one side of the body (6) is providedwith a turning mirror (501) covering the first channel and the second channel, and the other side of the body (6) is provided with a coupling output mirror (101) coinciding with the axis of the firstchannel and a total reflection mirror (401) coinciding with the axis of the second channel. According to the small folding cavity human eye safety laser, the length of the laser resonant cavity is increased within the limited length through the folding mirror, the turning mirror and the total reflection mirror, and small-size, light-weight and stable laser output is achieved.
Description
technical field [0001] The invention belongs to the technical field of eye-safe lasers, and more particularly relates to a small folded cavity eye-safe laser. Background technique [0002] Laser rangefinders are devices equipped with lasers. Eye-safe laser rangefinders are mainly divided into five categories in the military: handheld, ground vehicle, anti-aircraft artillery, airborne and shipborne. Military eye-safe solid-state lasers are widely used in military laser ranging, military laser irradiation, military imaging and other technical fields, and their development direction is miniaturization, integration, and lightweight. [0003] However, the existing lamp-pumped flat-cavity eye-safe solid-state lasers are generally relatively large in size, which is difficult to meet the volume and weight requirements of military eye-safe solid-state lasers, and it is difficult to debug, and the laser stability is poor under harsh environmental conditions. .
