Abstract: Laser treatment appliance having an illumination system, in particular for use in the field of medicine, has a laser light source for producing a treatment laser beam which is guided essentially freely, as well as an illuminating light source for producing a visible light for illuminating an area to be treated, and one or more first optical elements via which the treatment laser beam is passed on, with at least one of the first optical elements being in the form of an optical multifunction element, such that the visible light for illumination is also steered at least over this at least one optical multifunction element. The laser treatment appliance furthermore has an optical evaluation apparatus for diagnosis or analysis of radiation which is produced during the treatment process, and all the optical multifunction elements are designed such that they influence the treatment laser beam and the visible illuminating light essentially in an equivalent reflecting and/or transmitting manner.

Abstract: A medical laser treatment appliance which can be switched between a continuous wave (cw) operating mode and a pulsed operating mode and has at least one first laser light source for producing a cw laser beam, with the laser treatment appliance furthermore having a second laser light source for producing a pulsed laser beam, which is pumped by at least one first laser light sources, and the cw laser beam from at least one of first laser light sources is used for treatment in the cw operating mode, and the pulsed laser beam from the second laser light source is used for treatment in the pulsed operating mode, with the laser treatment appliance being designed such that the laser light source is also pumped continuously in the cw operating mode by at least one of the first laser light sources.
