Abstract

The invention discloses an active cavity traveling wave field enhanced gas Raman detection device. The device comprises a high-precision cavity, a detected gas chamber, a Raman light field collection part, a photoelectric detector and an analysis unit for collecting and analyzing Raman signals. According to the active cavity traveling wave field enhanced gas Raman detection device disclosed by the invention, an active laser resonant cavity mechanism is adopted, and a traveling wave light field and detected gas molecules interact so that a light field in a detected area has a relatively good uniformity characteristic, and the detection reliability and the anti-interference capability are enhanced; the active light field can interact with detected gas molecules in two directions in the two-way propagation process, the photon density of the light field in the cavity is high, the interaction effect is further improved through a two-way effect, gas Raman signals are improved, cavity-enhanced gas Raman detection is achieved, the gas Raman effect can be further remarkably improved, high-sensitivity gas Raman detection is realized, and maintenance brings a better use prospect.

Description

technical field [0001] The invention relates to the field of gas detection, in particular to an active cavity traveling wave field enhanced gas Raman detection device. Background technique [0002] With the rapid development of social economy, people's awareness of the protection of the ecological environment has gradually increased, making the application value of gas concentration detection increasingly enhanced. The detection of gas concentration in the production and living environment is very important for the safety of people's lives and property, the development of the national economy and the natural environment. Environmental protection is of great significance. In order to facilitate people to detect gas concentrations, some gas Raman detection devices have been invented; [0003] Existing gas Raman detection devices have certain disadvantages in use. When the existing gas Raman detection devices detect, there will be standing wave nodes in the light field. The det...
