摘要：

The use of a spider silk allows the direct observation of the dynamics induced by the transfer of angular momentum of laser light in a Beth-type experiment. In the optical domain, a uniform angular acceleration of a macroscopic object is demonstrated in agreement with the expected equation of motion. The intrinsic angular momentum exerts a stable torque thats modulus can be continuously adjusted from 0 to 10(-12) N m by changing the optical power. Moreover, a macroscopic no-node mirror is proposed to improve the optical angular momentum transfer in micro-manipulation in the context of optical tweezers. (c) 2005 American Institute of Physics.
