    摘要: A method for optical excitation of fluorophore-labeled DNA and fluorophore-labeled RNA, particularly of specific localizations of DNA and RNA labeled by fluorescence in situ hybridization (FISH). It is the object of the method to make possible in a simple manner a high-contrast simultaneous excitation of a plurality of FISH fluorophores which have different fluorescence characteristics and are to be detected and displayed three-dimensionally. The excitation and detection of fluorophores at a depth of the biological material greater than 100 micrometers must be ensured. The FISH fluorophores and DNA markers are excited to fluorescence by a multiphoton excitation simultaneously by pulsed and non-pulsed radiation at a single wavelength in the range between 700 nm to 1000 nm, preferably between 760 nm and 820 nm. A total of 20 commercially available FISH fluorophores and DNA markers were tested. Fluorophores which were excited simultaneously by multiphoton excitation were detected in all tested cases.

    摘要: The invention relates to a process for minimally invasive to non-invasive optical treatment of tissues of the eye and also for diagnosis thereof and to a device for implementing this process. The object underlying the invention is to create a process and a laser arrangement for minimally invasive to non-invasive optical treatment in the interior of the eye, particularly of cases of defective vision, by ablation of tissue, said treatment being distinguished by a hitherto unattained high precision, with possible widths of incision in the range less than 2 μm, without a significant mechanical impairment of the surrounding tissue occurring that has been generated by photodisruption. The process and the arrangement are to be inexpensive and easy to operate. In addition, at the same time the arrangement is to enable a three-dimensional imaging of the tissue. This object is achieved by virtue of a process in which the ablation is effected by focused planar or spatial scanning while adhering to equal, in order of magnitude, focusing-point diameters and point spacings below 5 μm with a radiation within the spectral range from 500 nm to 1200 nm, whereby, by virtue of a pulse duration in the order of femtoseconds and an energy of the individual pulse in the order of nanojoules and below, the destruction of the tissue is substantially limited to the diameter of the point, and permanent changes by virtue of propagation of energy beyond this diameter are avoided. The invention can be applied in opthalmology.
