Abstract: A Q-switched solid state laser is disclosed comprising a pump radiation source, whose pump radiation is focused through focusing elements in the laser crystal, a resonator formed by reflecting surfaces in which at least one laser crystal, an acousto-optic switch for Q-switching, and, if desired, a freqency-doubling crystal (KTP) are arranged. The acousto-optic Q-switch is connected with an electronic unit generating a high-frequency wave which can be modulated. The Q-switch is controlled by the high-frequency wave in such a way that laser pulses with pulse lengths on the order of magnitude of several microseconds (&mgr;s) and with an energy content on the order of magnitude of several millijoules can be generated by controlling the steepness of the edge of the modulation function of the high-frequency wave.

Abstract: A medical laser therapy device, particularly for use in ophthalmology and surgery, comprises a controllable pump module with a coupling element for a waveguide, a beam control device in the form of a waveguide for supplying the pumping radiation delivered by the pump module to the applicator which is provided with a coupling element for the waveguide for introducing a target beam and/or treatment beam into the eye to be treated.

Abstract: The invention is directed to a laser slit lamp comprising a slit lamp base, a slit lamp head and a slit lamp microscope. The laser slit lamp is connected with an applicator. It comprises means for uniting radiation from at least two radiation sources collinearly and for directing the radiation of a treatment beam or working beam onto the location to be treated in or on the eye of a patient, means for generating a target beam or marking beam for targeting and observing the location to be treated in or on the eye, and adjusting means in the applicator for changing the intensity and diameter of the working beam spot used for treatment. The radiation sources are laser radiation sources arranged in the slit lamp head, in the slit lamp base or in the slit lamp microscope for generating the working beam, illumination beam and/or target beam. Devices for control, regulation and monitoring are likewise arranged in the interior of the slit lamp.
