METHOD AND DEVICE FOR LASER-COOLING OF ATOM, AND COHERENT LIGHT SOURCE USED FOR LASER-COOLING OF ATOM

摘要

PROBLEM TO BE SOLVED: To allow laser cooling of various atoms including semiconductor atoms such as silicon and germanium.;SOLUTION: In this method of laser-cooling the atoms having a plurality of magnetic sublevels as the cooling lower level of a ground state on an energy level, coherent light of prescribed wavelength having a plurality of different polarized light corresponding to a plurality of magnetic sublevels which are the cooling lower level of the ground state of the atoms to be laser-cooled are irradiated on the atoms in regular sequence with a time lag at prescribed time intervals.;COPYRIGHT: (C)2003,JPO
