Abstract

The invention relates to a coupling dual-wavelength laser frequency stabilization light path system and method based on polarization spectroscopy. A first half-wave plate is arranged on a light path of a first laser. A first polarization beam splitter prism is arranged on a light path of the first laser passing through the first half-wave plate and used for splitting the first laser into detection light and pump light. A chopper is arranged on a light path of the pump light. A quarter-wave plate is arranged on a light path of the pump light passing through the chopper. A dichroscope is arranged on the light path of the pump light passing through the quarter-wave plate, is arranged on the light path of the second laser and is used for combining the pump light and the second laser to form combined light. A hollow cathode lamp is arranged on the light path of the combined light and the light path of the detection light. The cross point of the combined light and the detection light is at the central position of the hollow cathode lamp. A second half-wave plate is arranged on a light path of the detection light passing through the hollow cathode lamp. A photoelectric detector is arranged on a light path of the detection light passing through the second half-wave plate.

Description

technical field [0001] The present application relates to the field of laser technology, in particular to a coupled dual-wavelength laser frequency stabilization optical path system and method based on polarization spectroscopy. Background technique [0002] The stability of laser frequency is crucial in many fields such as atomic physics, quantum computing, and precision measurement. Among them, laser cooling and state preparation in ion trapping experiments require light of a specific frequency, and the laser frequency stability is relatively high, so a frequency stabilization system needs to be established to obtain the corresponding laser. For the jitter and drift of laser frequency caused by environmental factors such as temperature, pressure, vibration, etc., a stable absolute frequency can generally be used as a reference, such as the transition line of an atom or molecule. Or use a calibrated relative frequency as a reference, such as an interferometer in an optical...
