Abstract:
A medical laser therapy device comprising:a controllable pump module with a coupling element for a waveguide; an applicator with a coupling element for the waveguide for introducing a target beam and/or treatment beam into an eve to be treated; a beam control device in the form of a waveguide for supplying the pumping radiation delivered by the pump module to the applicator; said pump module having laser diodes whose electromagnetic pumping radiation is in the spectral range from 800 nm to 815 nm; an optics module being provided which couples the pumping radiation into the waveguide; said beam control device being an Nd-doped waveguide laser with a double core or single core and a suitable reflecting coating of the fiber end faces; said waveguide forming a laser cavity with radiation in a frequency range between 1050 nm and 1070 nm; said applicator being a laser slit lamp with zoom system having a device for frequency doubling which comprises nonlinear optical material or periodically poled nonlinear optical material; said applicator having a device for power monitoring; said applicator having a device for illuminating and observing the operating field; and said applicator also having a target beam device whose radiation is coupled collinearly into the beam path for the therapy radiation by a suitable beamsplitter.
