WebMar 29, 2024 · Optical dipole traps rely on the induced atomic electric dipole interaction with electric component of the trapping light. The power needed for trapping depends on the desired trap depth and the detuning from the nearest optical transitions. WebAn optical vortex (OV) is a typical singular structure that may occur in paraxial beams [ 8, 9, 12 ]. OV is the scalar singularity, which can exist independently of the beam polarization. In a circular OV, the scalar complex amplitude (2) is characterized by the “helical phase factor” shutterfly team share site
