The cooling laser enters the integrated collimating lens barrel through the optical fiber, and then the power of the light beam is uniformly split through a half wave plate and a polarization beam splitter prism in the lens barrel. Two bundles of light pass through corresponding quarter wave plate respectively, form circular polarization light, then rethread two-dimentional magneto-optical trap cavity (contain gradient magnetic field distribution), pass through quarter wave plate again, return incident light through the high mirror of zero degree again to form the laser standing wave field with atom steam interact, when passing atom steam, laser and atom steam interact, slow down the cooling to atom steam in two perpendicular directions, thereby form slow-speed atom and restraint, enter into three-dimensional magneto-optical trap through two-dimentional magneto-optical trap cavity export.
