The Measurement of Weak Absorption Spectroscopy Using Intensity Difference Squeezed Light
A method is propose in this paper for high sensitive absorption spectrum analysis using intensity difference squeezed light. It has been evidence with a semiclassical theoretical calculation that the sensitivity of measurement can be beyond the limit set by vacaum fluctuation and the minimum detectable absorptance is below the SNL.
