Abstract

We study laser cooling of ²⁴Mg atoms in dipole optical trap with pumping field resonant to narrow (3s3s) ¹S₀ → (3s3p) ³P₁ (λ= 457 nm) optical transition. For description of laser cooling of atoms in the optical trap with taking into account quantum recoil effects we consider two quantum models. The first one is based on direct numerical solution of quantum kinetic equation for atom density matrix and the second one is simplified model based on decomposition of atom density matrix over vibration states in the dipole trap. We search pumping field intensity and detuning for minimum cooling energy and fast laser cooling.
