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

IEEE 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.

Technical Study on Dual-Mirror Cooperative Frequency-Stabilized Induced Backscatter Angle Control for Locking Zones

IEEE Photonics Journal
The backscatter-induced lock-in effect constitutes a primary error source in laser gyroscopes, with the lock-in threshold critically dependent on the magnitude of the backscatter angle. Conventional dual-mirror synchronous frequency stabilization suffers

High bandwidth frequency modulation of an external cavity diode laser using an intracavity lithium niobate electro-optic modulator as output coupler

APL Photonics, 2022
We present a novel approach to high bandwidth laser frequency modulation. A lithium niobate chip is used as an intracavity electro-optic modulator in a tunable cateye external cavity diode laser.

Analysis and Improvement of Frequency Stabilization Characteristics of a Total Reflection Prism Laser Gyro

IEEE Access, 2018
To rectify the low accuracy of frequency stabilization for a total reflection prism laser gyro (TRPLG), a mathematical model for TRPLG frequency stabilization was established. Wavelet filtering was introduced into the phase-sensitive demodulation process,

Designing an Automatic Frequency Stabilization System for an External Cavity Diode Laser Using a Data Acquisition Card in the LabVIEW Platform

Applied Sciences, 2023
The frequency stability of free-running lasers is susceptible to the influence of environmental factors, which cannot meet the long-term frequency stabilization requirements for atom interferometry precision measurements. To obtain a frequency-stabilized
