Abstract

Abstract

The experimental system of dual-beam fiber optical trap is proposed and built for the first time which can realize the trapping and manipulation of polystyrene microspheres by taking the supercontinuum laser as the trapping light source. The position of the microsphere is manipulated by changing the relative position of the two optical fiber end faces and output power of the fibers. The CCD image analysis method is used to measure the position of the microsphere. The power spectrum is calculated by Fourier transform of the position variation of the confined Brown motion. After fitting the theoretical power spectrum function, the optical trap stiffness is obtained. The results show that when the power of the captured beam is 28 mW, the optical trap stiffness can reach 1.3×10 ^-6N/m, which is higher than that of the single wavelength optical trap under the same experimental conditions. By taking advantage of the wide spectrum of the dual-beam optical trap system, the physical parameters such as the size and refractive index can be obtained by studying the scattering spectrum information of the captured particles which is different from the traditional use of monochromatic light as the captured light of the optical tweezers.
