Abstract

The invention discloses a foldable dual-beam magnetic light trap system which is mainly suitable for generating cold atoms in laser cooling. Three pairs of laser with opposite polarization and opposite travelling are formed in a vacuum chamber through reflecting incoming laser many times, and a magnetic light trap is formed under the mutual action of a magnetic field generated by an opposite Helmholtz coil. The foldable dual-beam magnetic light trap system is characterized in that multiple reflections are utilized, and laser energy is repeatedly utilized, thereby obtaining the cold atoms. Theinvention has the advantages of simple structure, easy power balance, stable atomicgroup, low input power of laser and easy adjustment, thereby providing a better cold atom resource for cold atom frequency scale, precise measurement and laser cooling physical test.

Description

technical field [0001] The invention relates to a magneto-optical trap system, which belongs to the generation technology of ultracold atoms. In particular, a folded double-beam magneto-optical trap system. [0002] It is characterized in that the laser power required to form a magneto-optical trap is reduced by using multiple reflections of the incident laser light, and the power balance and stability of the relative laser beam are increased while the laser power is reused, so as to obtain better and more stable cooling. atomic source. It has the characteristics of low power consumption, simple structure, easy adjustment and good stability, and provides a better experimental platform for atomic frequency standard, precision measurement and cold atomic physics experiments. Background technique [0003] The rapid development of laser cooling and confinement technology in the past 30 years has greatly promoted the development of atomic physics, atomic frequency standards, an...
