Abstract
In order to measure aerosol extinction coefficients with higher sensitivity , a system for measuring aerosol extinction coefficients was set up based on high-reflectivity cavity mirrors and pulse cavity ring-down technology .The actual atmosphere under different conditions was measured .The experimental results were analyzed and studied , and compared with the research results at home and abroad .The results of the experiment show that cavity ring-down time is greater than 40μs, stability is better than 0.3%and detection sensitivity is greater than 1.8 ×10 -7 m–1 .Cavity mirrors with high reflectivity and pulse cavity ring-down technology are quite feasible in development of detection systems of aerosol extinction coefficients with high sensitivity .关键词
