A laser motivated by noise

We explain a work on Nonlinear Quantum Optics, which provides a detailed examination of the squeeze laser and the underlying physics of its optical resonator. Going through key operational concepts, such as the maximization of squeezing capacity through the use of non-linear crystals, which can theoretically produce highly compressed quantum states over short distances. Much of the analysis is dedicated to the technical requirements for stable operation, including the calculations for the Gaussian beam profile and the resonator stability criterion based on mirror curvature and separation. A central feature is the principle of impedance matching, which, when achieved, results in zero light reflection and is the condition required for the ideal damping of quantum field uncertainty. This precise mechanism allows the device to generate powerful squeezed light when operated just below the oscillation threshold of the optical parametric oscillator.
