TL;DR
This paper introduces the concept of a 'quiet laser' that produces regular photo-electrons, and analyzes various configurations using semi-classical physics, showing agreement with quantum optics results.
Contribution
It defines and analyzes the 'quiet laser' concept within a semi-classical framework, aligning with quantum optics findings.
Findings
Quiet lasers produce sub-Poisson photo-electron statistics.
Laser power stability is linked to the regularity of emitted electrons.
Semi-classical analysis matches quantum optics results.
Abstract
We call "quiet laser" a stationary laser that generates in detectors regular photo-electrons (sub-Poisson statistics). It follows from the law of conservation of energy that this is so when the laser power supply does not fluctuate. Various configurations are analyzed on the basis of the Planck (1907) semi-classical concept: "I am not seeking the meaning of light quanta in the vacuum but rather in places where emission and absorption occur, and I assume that what happens in the vacuum is rigorously described by Maxwell's equations". Exact agreement with Quantum Optics results is noted. Comments welcome!
