... We now want to consider the effects of irradiating an all trans sample at its absorption wavelength. If the extinction coefficients of the cis and trans isomers are unknown at that wavelength, then we have no direct way of determining the amount of cis isomer produced.

Atomic Quantum Metrology with Narrowband Entangled and Squeezed States of Light DISSERTATION
... per second N is measured, the intrinsic error or quantum noise will be N . Photons in a laser beam and rain drops follow the same behavior as they are both governed by the statistics of random √ independent events: the Poisson distribution. The N -limit is generally called shot-noise limit and in qu ...

This requires a larger relative excitation bandwidth. However, the relative excitation bandwidths of pulses in the radio frequency (rf) and mw r ...
