摘要
提出一种应用强度差压缩态光场进行高灵敏度吸收光谱分析的方案,并通过半经典理论分析证明,该方案的测量灵敏度不受真空起伏限制,最小可测吸收系数低于光波场的散粒噪声极限。
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.
