An active solid state ring laser gyroscope
Abstract
The properties of an active, solid state ring laser gyroscope were investigated. Two laser diode pumped monolithic nonplanar ring oscillators (NPRO), forced to lase in opposite directions, formed the NPROGyro. It was unique in being an active ring laser gyroscope with a homogeneously broadened gain medium. This work examined sources of technical and fundamental noise. Associated calculations accounted for aspects of the NPROGyro performance, suggested design improvements, and outlined limitations. The work brought out the need to stabilize the NPRO environment in order to achieve performance goals. Two Nd:YAG NPROs were mounted within an environment short term stabilized to microdegrees Celsius. The Allan variance of the NPROGyro beat note was 500 Hz for a one second time delay. Unequal treatment of the NPROs appeared as noise on the beat frequency, therefore reducing its rotation sensitivity. The sensitivity to rotation was limited by technical noise sources.

We report an experimental and theoretical study of a rotating diodepumped NdYAG ring laser with active beatnote stabilization. Our experimental setup is described in the usual MaxwellBloch formalism. We analytically derive a stability condition and some frequency response characteristics for the solidstate ringlaser gyroscope, illustrating the important role of mode coupling effects on the dynamics of such a device. Experimental data are presented and compared with the theory on the basis of realistic laser parameters, showing very good agreement. Our results illustrate the duality between the very rich nonlinear dynamics of the diodepumped solidstate ring laser (including chaotic behavior) andmore »

Suppression of Nonlinear Interactions in Resonant Macroscopic Quantum Devices: The Example of the SolidState Ring Laser Gyroscope
We report finetuning of nonlinear interactions in a solidstate ring laser gyroscope by vibrating the gain medium along the cavity axis. We demonstrate both experimentally and theoretically that nonlinear interactions vanish for some values of the vibration parameters, leading to quasiideal rotation sensing. We eventually point out that our conclusions can be mapped onto other subfields of physics such as ringshaped superfluid configurations, where nonlinear interactions could be tuned by using Feshbach resonance. 
A mathematical model of the dynamics of an optically pumped codoped solidstate laser system
This is a study of a mathematical model for the dynamics of an optically pumped codoped solid state laser system. The model comprises five first order, nonlinear, coupled, ordinary differential equations which describe the temporal evolution of the dopant electron populations in the laser crystal as well as the photon density in the laser cavity. The analysis of the model is conducted in three parts. First, a detailed explanation of the modeling process is given and the full set of rate equations is obtained. The model is then simplified and certain qualitative properties of the solution are obtained. In themore » 
Stochastic and chaotic effects in the ring laser
Experimental and theoretical distinctions are drawn between chaotic and stochastic laser processes. Elementary notions of stochastic and chaotic processes are introduced and the relevant laser theory is outlined. The spontaneous switching between the two counterpropagating cavity modes in the bidirectional dye ring laser is experimentally shown to be a stochastic rather than a chaotic process  a macroscopic manifestation of quantum fluctuations. However, the rapid intensity fluctuations in the laser are experimentally demonstrated to be chaotic. The underlying source of this behavior is the turbulent flow of the dye through the dye cell. For the standing wave singlemode dye laser,more » 
Homogeneously broadened bidirectional ring laser: Theoretical analysis, numerical simulation, and experiment in heliumxenon
Theoretical and experimental studies of a homogeneously broadened bidirectional ring laser are reported. A model for a homogeneously broadened bidirectional ring laser is derived. The material variables, the population inversion and the atomic polarization, are written as infinite spatial harmonic series. Each of those series is truncated at fourth order in the spatial frequency, yielding a system of fifteen real equations. A numerical investigation of the validity of this truncation is performed. The rate of convergence of the spatial harmonic series of the population inversion and thereby the validity of the truncation of the series, is found to depend onmore »
