Abstract
The technique of laser manipulation of individual dust particles instrongly coupled dusty plasmas is presented and its application to differenttypes of experiments is demonstrated. The laser manipulation has been used toexcite horizontal compressional waves and Mach cones which are used to derivethe horizontal particle interaction and screening strength. Lasers are alsoused to excite collective modes in finite Coulomb clusters (`artificialatoms'). From the laser excitation of vertical oscillations in the sheath ofan rf discharge the dust particle charge is measured. Moreover, the verticalinteraction between dust particles is shown to be non-reciprocal andattractive due to the ion streaming motion in the sheath where the dustparticles are trapped.
