Study of the Steady-State Operation of a Dual-Longitudinal-Mode and Self-Biasing Laser Gyroscope

open access: yesSensors, 2022
In order to stabilize the self-biasing state of a laser gyroscope, a dual-longitudinal-mode asymmetric frequency stabilization technique was studied. The special frequency stabilization is based on the accurate control of the intensity tuning curve in ...

The Complex Way to Laser Diode Spectra: Example of an External Cavity Laser With Strong Optical Feedback [PDF]

open access: yes, 2005
An external cavity laser with strong grating-filtered feedback to an antireflection-coated facet is studied with a time-domain integral equation for the electric field, which reproduces the modes of the oscillation condition as steady-state solutions ...

Steady-State Analysis of the Effects of Residual Amplitude Modulation of InP-Based Integrated Phase Modulators in Pound–Drever–Hall Frequency Stabilization

open access: yesIEEE Photonics Journal, 2019
Residual amplitude modulation of the phase modulator deployed in Pound–Drever–Hall frequency stabilization is an effect known to cause instabilities to the absolute wavelength of the stabilized laser. We present measurements and analysis of

Carrier-Envelope Offset Frequency Stabilization of a Thin-Disk Laser Oscillator via Depletion Modulation

open access: yesIEEE Photonics Journal, 2020
We present a novel concept for the stabilization of the carrier-envelope offset (CEO) frequency of femtosecond pulse trains from thin-disk laser oscillators by exploiting gain depletion modulation in the active gain region.

Slow light frequency reference cavities—proof of concept for reducing the frequency sensitivity due to length fluctuations

open access: yesNew Journal of Physics, 2022
Length changes due to thermo-mechanical noise originating from, for example, Brownian motion are a key limiting factor of present day state-of-the-art laser frequency stabilization using Fabry–Pérot cavities.

A Case Study on the Application of 3D Scanning Technology in Deformation Monitoring of Slope Stabilization Structure

open access: yesBuildings, 2023
Traditional deformation monitoring suffers from issues such as the point-based representation of surfaces and low measurement efficiency. Moreover, the majority of researchers study the deformation of slopes using methods such as 3S technology, synthetic

Volume Bragg grating external cavities for the passive phase locking of high-brightness diode laser arrays : theoretical and experimental study [PDF]

open access: yes, 2011
We describe the theoretical modeling of the external-cavity operation of a phase-locked array of diode lasers in two configurations, the self-imaging cavity based on the Talbot effect and the angular-filtering cavity. Complex filtering functions, such as

Stability of Continuously Pumped Atom Lasers [PDF]

open access: yesPhysical Review Letters, 2002
A multimode model of a continuously pumped atom laser is shown to be unstable below a critical value of the scattering length. Above the critical scattering length, the atom laser reaches a steady state, the stability of which increases with pumping. Below this limit the laser does not reach a steady state. This instability results from the competition
