Raman sideband cooling is a method to prepare atoms in the vibrational ground state of a periodic potential and cool them below recoil limit. It can be implemented inside an optical dipole trap where cooling with less loss of trapped atoms could be achieved in comparison to evaporative cooling, can be implemented as a mid-stage cooling to improve the efficiency and speed of evaporative cooling, and is generally extremely insensitive to the traditional limitations of laser c… WebSub-Doppler cooling techniques have been developed for potassium, but dipole trap loading remains inefficient due to the low initial density. To this end, we have developed and built a trapping field using an octupole magnetic field, which combines elements of both near-zero fields at the trap center for sub-Doppler cooling, and restoring ... scrap yard rochester nyWebDegenerate Raman sideband cooling This more specific cooling scheme starts from atoms in a magneto-optical trap, using Raman transitions inside an optical lattice to bring … scrap yard rockmart ga
