The entrapment of radiation will make a photon be emitted and resonance-reabsorbed many times inside the laser material.
Suppression of the potential well prevents the free electrons from recombination and, thus, no high-energy photon can be emitted.
The situation is radically different if electrons are emitted by such a plasma.
The emitted fluorescence light is directed to a photomultiplier.
Since the frequency of the signals emitted by the baroreceptors is known, this can be done spectrally, if the coupling is linear.
Then optical filters are inserted before emission can reach the detectors in order to select the emitted wavelength for a specific acquisition channel.
One detection scheme presently in use requires optical band-pass filters appropriately designed to bin emitted fluorescence photons of desired target molecules.
