摘要: We describe a single‐sideband frequency demodulation scheme with large dynamic range which gives linear response and is capable of shot‐noise‐limited performance when used with time‐resolved pump and probe, polarization, and three‐ and four‐wave mixing spectroscopies.关键词:...
The limited detectionbandwidthcan lead to reduced noise at high frequencies. There is also some detector noise added, which occurs even without any optical input (see below).

Here we present a mid-IR Faraday rotation spectrometer (FRS) for detection of NO isotopes. The instrument utilizes a novel dual modulation/demodulation (DM) FRS method which exhibits noise performance at only 2 times the fundamental quantum shot-noise level and provides the record sensitivity in ...

A fundamental challenge in fluorescence microscopy is the photon shot noise arising from the inevitable stochasticity of photon detection. Noise increases measurement uncertainty and limits imaging resolution, speed and sensitivity. To achieve high-sensi
We use a hysteretic Josephson junction as an on-chip detector of the third moment of shot noise of a tunnel junction. The detectable bandwidth is determined by the plasma frequency of the detector, which is about 50 GHz in the present experiment. The third moment of shot noise results in ...
