Magneto-optical trap mot
WebWe report the experimental realization of 88Sr magneto-optical trap (MOT) operating at the wavelength of 461 nm and 689nm. The blue MOT is loaded via a 32 cm long spin-flip type Zeeman slower which enhances the MOT population by a factor of 44. We have trapped 1.6×108 88Sr atoms with the use of 679nm and 707nm repumping laser. WebThe first proposal for a molecular magneto-optical trap (MOT) identified five classes of diatomic molecules as being amenable to laser cooling and trapping [14], includ-ing halides, hydrides, oxides, carbides, and sulfides. However, only the fluorides SrF [15] and CaF [16–18] have thus far been loaded into 3D MOTs. Since the initial

WebDifferent types of atom trap have been designed. The most often used is the Magneto-Optical Trap (MOT). In a MOT, trapping is accomplished with three pairs of counter-propagating laser beams and an inhomogeneous magnetic field. A collection of sodium atoms (yellow dot in middle of picture) trapped in a MOT. WebValidation. Each chip supplied with actual atom number and cooling data. This work was published in Nature Nanotechnology. Grating Magneto-Optical Trap. Laser cooling is greatly simplified, requiring only one laser beam incident on the grating for each stage of laser cooling. The other required beams are generated by diffraction from the grating.
WebJul 15, 2007 · A mirror magneto-optical trap (MOT) that exploits a hexapole-compensated magnetic field was developed and used in the experimental surface trapping of neutral atoms. A pair of subsidiary wires, which was placed near the main current-carrying wire, was designed to improve the uniformity of the quadrupole magnetic field and thus increased … WebJun 1, 2024 · A MOT relies on dissipative scattering of thousands of photons from lasers that are tuned into or out of resonance according to the molecules’ positions and velocities in a quadrupole magnetic...
