Claims (1)

25 claims A laser emitting device in a semiconductor laser treatment unit, comprising a housing in which η 30 semiconductor lasers with collimating lenses are located and a focusing lens, the focus of which has the ability to focus the radiation of all lasers, characterized in that the aim is to increase efficiency laser radiation, η holders are introduced into it, with the help of which each semiconductor laser with a collimating lens forms a 4θ laser module, and η landing apertures arranged in a circle, the center of which lies on the optical axis of the focusing lens, and a plane at which 45 lies a circle is perpendicular to it, laser modules are tightly placed in the mounting holes so that the directions of the collimated 5θ laser beams are parallel to the optical axis of the focusing lens.
