摘要： The invention provides a laser system (100) wherein the output may be selected from two or more different wavelengths of output laser light. The system (100) comprises a laser capable of having at least two different wavelengths of laser light resonating in the cavity (105) simultaneously. One of the frequencies is generated by a Raman crystal (135) which shifts the frequency of light generated by the lasing medium (125). A tunable non-linear medium (140), such as LBO, is provided in the cavity for selectively frequency converting at least one of the at least two different wavelengths of laser light. The conversion may be SHG, SFG or DFG for example. A tuner (145) is provided.to tune the non-linear medium to select the particular wavelength to convert. Temperature tuning or angle tuning of the non-linear medium can be used. A Q switch (130) may also be provided in the cavity. The output laser beam can be used for treatment, detection or diagnosis of a selected area on or in a subject, and can b used in ophthalmological and dermatological fields.

摘要： A fluorescence detection system comprises a light source (22), dichroic mirror (32), excitation port (16), emission port (14), and a detector. The light source (22) is, for example, a pulsed ultraviolet LED, with a light emission that decays sufficiently rapidly to permit gated detection of fluorescence from a fluorescently-labelled species, at a time when it is distinguishable from autofluorescence. The detector is, for example, an electron multiplying CCD, with high gain on- chip amplification. A circuit (26) may be used to control a repeating cycle of (i) generation of a 20-200 microsecond UV. pulse; (ii) a gate delay of 1-5 microseconds; and (iii) a 10-800 microsecond detection period. This allows time- resolved-fluorescence-microscopy with real time or near real time operation.
