A laser acupuncture therapeutic instrument, comprising: a laser (8) a collimating mirror (9), which is arranged on a light emergent end of the laser (8) and converts a laser emitted by the laser (8) into a parallel laser beam a laser polarizer (11), which is arranged on a light emergent end of the collimation mirror (9) and converts the parallel laser beam into a first linearly polarized laser (11-1) and second linearly polarized laser (11-2), wherein a polarization direction of the first linearly polarized laser (11-1) is different from a polarization direction of the second linearly polarized laser (11-2) and a laser beam combiner (13), which is arranged on a light emergent end of the laser polarizer (11) and is used for performing beam combination on the first linearly polarized laser (11-1) and the second linearly polarized laser (11-2). The laser acupuncture therapeutic instrument can obtain a crossed polarized-state laser, and can improve the effect of laser acupuncture. The laser acupuncture therapeutic instrument can adjust and control the intensity and a combination direction of polarized light through rotation, and output a polarized laser at a main polarization axis with a stable power, thereby achieving a brand new effect of acupuncture.Linvention concerne un instrument thérapeutique dacupuncture laser, comprenant : un laser (8) un miroir de collimation (9), qui est disposé sur une extrémité démergence de lumière du laser (8) et convertit un laser émis par le laser (8) en un faisceau laser parallèle un polariseur à laser (11) qui est disposé sur une extrémité démergence de lumière du miroir de collimation (9) et convertit le faisceau laser parallèle en un premier laser à polarisation linéaire (11-1) et un second laser à polarisation linéaire (11-2), une direction de polarisation du premier laser à polarisation linéaire (11-1) étant différente dune direction de polarisation du second laser à polarisation linéaire (11-2) et un combinateur de faisceau laser
