Method for simultaneously measuring HF rotation temperature and vibration-level particle number distribution

Abstract

The invention relates to a method for simultaneously measuring HF rotation temperature and vibration-level particle number distribution. The method is based on a spontaneous radio fluorescence spectrum technology and is a novel method for simultaneously measuring HF molecular rotation temperature and vibration-level particle number distribution through a straight-line graphic method. The method is mainly applied to the technical field of HF chemical laser testing and diagnosis, can simultaneously measure the rotation temperature and vibration-level particle number distribution, and can carry out plotting only by simply processing the P branch spectrum line intensity of each vibration and rotation spectrum band of an HF base frequency spontaneous radio fluorescence spectrum. The method has the advantages of being simple and convenient to implement, visual, accurate, non-invasive and the like. By the adoption of the method, simultaneous and rapid measurement of rotation temperature in an HF chemical laser and vibration-state each-level particle number distribution can be achieved.

Description

technical field [0001] The invention relates to a measuring and diagnosing technology of HF chemical laser, in particular to a method for simultaneously measuring HF rotation temperature and vibration energy level particle number distribution. The HF fundamental frequency transition radiation spectrum measured by Fourier transform infrared spectrometer can be used to monitor the rotation temperature T of HF molecules and the particle number distribution of vibrational excited states such as v=1,2,3, so as to monitor HF chemical lasers operating performance. Background technique [0002] Since the first chemical laser came out in 1964, the development of chemical lasers has been advancing by leaps and bounds, and the speed is astonishing. Among them, the development of HF chemical lasers is the most mature. The American Alpha HF chemical laser with continuous wave output power up to MW level was once a laser Synonymous with weapons. [0003] The main operating principle of ...
