  • The radiation torque induced by a focused laser beam has been widely utilized for the optical manipulation of small particles in various fields such as physics, biology, and optofluidics. To isolate the contribution of each scattering process to the radiation torque and to clarify the physical mechanism of radiation torque, the Debye Series Expand(DSE) is introduced to analysis of the radiation torque exerted on a homogeneous sphere by Gaussian beam. When Debye mode p ranges from 1 to a value pmax large enough, the result obtained by DSE is identical to that by Generalized Lorenz-Mie Theory(GLMT). Furthermore, the radiation torque corresponding to each Debye mode p is mainly analyzed. Results show that when incident beam is linearly polarized, all scattering processes for p in 1-5 can produce a transverse torque while the directions of torque are different. When the beam is circularly polarized, the torques for p in 1 and 0 are much larger than that for p in 1-4, and the direction of torque for p in 0 is opposite with that for other mode p.
