Abstract: A soft laser unit is described with a housing and a skin resistance measuring device for localizing acupuncture points which contains a probe electrode, a measuring circuit connected therewith and a display device connected to the latter. The unit additionally contains a biostimulation or therapy laser unit, in particular for laser acupuncture, and an exit opening for the laser beam of the laser unit with a focusing optic is provided within the probe electrode, whereby in the state mounted on the patient's skin the laser beam focus of the laser unit comes to lie generally in the plane of the face of the probe electrode, i.e. on the skin surface. The soft laser unit can also be utilized in continuous operation as a so-called “laser shower”, without touching the skin, by fixing the probe electrode in the pressed-in state.
