An optical tweezer for complex plasmas

Jan Schablinski, Frank Wieben and Dietmar Block

This paper describes the experimental realization of an optical trap for microparticles levitating in the plasma sheath. Single particles can be trapped in a laser beam comparable to optical tweezers known from colloidal suspensions. The trapping mechanism is discussed and two applications of the system are shown.
