Active contactless optical sorting of microobjects represents very useful technique in many areas of biology, chemistry, and medicine. We suggest here a configuration that combines optical sorting, trapping, excitation, and detection paths and provides efficient sorting of biological samples according to their various parameters (fluorescence, Raman spectrum, CCD image, motion etc.). This approach is based on the shape of the laser beam and we succeeded in sorting of several types of living microorganisms.
