Near-field Raman imaging using optically trapped dielectric microsphere.
The stumbling block of employing Raman imaging in nanoscience and nanotechnology is the diffraction-limited spatial resolution. Several approaches have been employed to improve the spatial resolution, among which aperture and apertureless near-field Raman techniques are the most frequently used. In this letter, we report a new approach in doing near-field Raman imaging with spatial resolution o...
متن کاملA spatial refractive index sensor using whispering gallery modes in an optically trapped microsphere
Microspheres can act as high Q resonators in the optical regime 2 and can store electromagnetic waves by repeated total internal reflection. Constructive interference results in an enhanced internal field which is called a whispering gallery mode (WGM). Because of the evanescent interaction between the WGM and the surrounding medium the WGM’s resonance frequency is sensitive to changes in the r...
متن کاملSympathetic cooling in an optically trapped mixture of alkali and spin-singlet atoms.
We report on the realization of a stable mixture of ultracold lithium and ytterbium atoms confined in a far-off-resonance optical dipole trap. We observe sympathetic cooling of 6Li by 174Yb and extract the s-wave scattering length magnitude |a(6Li-174Yb)|=(13±3)a0 from the rate of interspecies thermalization. Using forced evaporative cooling of 174Yb, we achieve reduction of the 6Li temperature...
متن کاملDoppler cooling a microsphere.
Doppler cooling the center-of-mass motion of an optically levitated microsphere via the velocity-dependent scattering force from narrow whispering gallery mode resonances is described. Light that is red detuned from the whispering gallery mode resonance can be used to damp the center-of-mass motion in a process analogous to the Doppler cooling of atoms. The scattering force is not limited by sa...
متن کاملRotation of two trapped microparticles in vacuum: observation of optically mediated parametric resonances.
We demonstrate trapping and rotation of two mesoscopic particles in vacuum using a spatial-light-modulator-based approach to trap more than one particle, induce controlled rotation of individual particles, and mediate interparticle separation. By trapping and rotating two vaterite particles, we observe intensity modulation of the scattered light at the sum and difference frequencies with respec...
