Abstract

An apparatus for characterising a sample, such as a flow cytometer or a microscope, comprises a laser, in particular a laser configured to emit solitons, for irradiating the sample with an optical pulse and an optical detector for detecting fluorescence radiation emitted by the sample as a consequence of said irradiation. The sample is excited by multiphoton excitation or a non-linear optical device is inserted between the laser and the sample for frequency conversion, thereby obviating the use of a UV laser. The apparatus optionally comprises pulse shaping elements like a pulse stretcher, a pulse amplifier, and a pulse compressor. Light transmission between the laser and the sample may be via optical fibres, in particular optical telecommunication fibres, wherein the light pulse may be distributed to a plurality of measurement heads by means of one or more optical multiplexers.
