Problems solved by technology

[0005] In the previous systems, there are usually two methods, one is to shape and expand the laser beam, and then enter the system from free space, because this kind of system is bulky and not conducive to shielding the geomagnetic field, it is generally used in magneto-optical traps; the other is One is through a fixed optical fiber adjustment head for vertical incidence, and then enters the system after expanding the b

Abstract

The invention relates to an optical beam-expanding collimation system for a cold atom physical experiment system in a magneto-optical trap structure, an optical trap structure and other structures, which is formed by connecting a laser-introducing system, a beam-expanding collimation system and a detection system by a bracket. The invention provides a basis for the modularized design of the cold atom physical system, enhances the adjustment, the expansibility and the detectability of the cold atom physical system, and has the advantages of simple structure, small size, convenient mounting and adjustment, high adjustment precision and good stability.

Description

technical field [0001] The present invention relates to magneto-optical traps, optical traps and other structural cold atomic physics experiment systems, in particular to a system for obtaining a large number of stable cold atomic groups with magneto-optical traps, optical traps and other lasers and real-time monitoring of laser intensity and stability. Sexual optical beam expander collimation system. Background technique [0002] In cold atomic physics, especially in cold atomic frequency standards, it is usually necessary to capture, imprison and cool down a large number of atoms for related physics in order to obtain longer action time, more stable and accurate experimental data. Cold atomic physics involves atomic fineness and energy levels, and the geomagnetic field will cause atomic energy levels to change. [0003] According to the theory of laser cooling, common methods of laser cooling atoms are divided into linear ⊥ linear polarization gradient cooling and σ accor...
