[0021] The traditional transmission cavity frequency stabilization method can only use a set of transmission cavity and a reference laser to lock a beam of laser to be stabilized, which wastes space and is costly. It is complicated to use whether the locked laser on the transmission cavity is unlocked

Abstract
The invention discloses a transmission cavity frequency regulator capable of carrying out frequency stabilization on multiple beams of laser, and relates to the field of laser frequency stabilization. The abstract attached diagram is a structure diagram of the transmission cavity frequency regulator capable of carrying out frequency stabilization on four beams of laser. The frequency regulator is composed of a transmission cavity (11), a reference laser (1), four lasers to be stabilized with different wave lengths (2, 3, 16 and 17), lenses (4, 5, 6, 18 and 19), reflector mirrors (7, 10, 20 and 21), spectroscopes (8, 9, 22 and 23), a piezoelectric controller (12), a calculation controller (13), a temperature controller (14) and a photoelectric detector (15). The transmission cavity frequency regulator capable of carrying out frequency stabilization on the multiple beams of laser has the advantages of being capable of simultaneously locking the frequencies of the multiple beams of laser, restraining long-time drifting of the frequencies of the multiple beams of laser, being convenient to use, saving space and lowering cost, and can be widely applied to the fields needing laser frequency stabilization such as laser physics, frequency standards and quantum information.
Description
Technical field [0001] The invention relates to laser frequency stabilization technology, and more specifically to a device that uses a transmission cavity to stabilize the laser frequency. It is suitable for laser physics, frequency standard, quantum information and other fields that require laser frequency stability. Background technique [0002] In precision spectroscopy experiments, multiple lasers with stable frequency are required. The long-term drift of laser frequency needs to be less than 1MHz / h. The long-term drift of free-running lasers in the laboratory is greater than 100MHz / h due to temperature changes and vibration effects. Therefore, Need to stabilize the laser frequency. Technically, it is possible to use Fabry-Perot cavity and saturated absorption for frequency stabilization, but it is more complicated, and it is difficult to find suitable atomic and molecular spectral lines to meet the needs of frequency stabilization. The use of transmission cavity for freque...
