Abstract

We demonstrate a fiber-optical version of a stable three-dimensional light-force trap, which we have used to hold and manipulate small dielectric spheres and living yeast. We show that the trap can be constructed by use of infrared diode lasers with fiber pigtails, without any external optics.
