What is atomic refractor?

An atomic refractor is a device that uses the principles of atomic optics to manipulate and control the properties of light. It typically consists of a vapor cell containing a sample of atomic gas, which is then illuminated with a laser beam. The laser light interacts with the atoms in the gas, causing them to change their energy levels and emit light of a specific frequency and polarization. By manipulating the laser beam and the properties of the gas, scientists can control and manipulate the frequency, intensity, polarization, and other properties of the emitted light, making it possible to generate highly precise and efficient sources of light for a variety of scientific and technological applications. Some of the common applications of atomic refractors include laser cooling and trapping of atoms, quantum information processing, and precision measurements of time, distance, and other physical quantities.
