摘要

基于120°相差干涉和光场相位实时重构的窄线宽激光动态噪声特性测试方法,从时域频率调谐函数、频域频率噪声功率谱密度及其随时间的演化特征等方面,研究线性扫频激光器在不同扫频方式下动态相频噪声的细节特性。实验结果表明,扫频机理或参数差异导致结果呈现完全不同的实时动态噪声特性。电光调制能够在反馈锁相环辅助下获得最佳的扫频线性度,但会引起反馈谐振峰等噪声恶化,其控制参数不同,反馈谐振峰频率等特征也会发生变化;声光调制呈现最小程度的噪声恶化;压电调谐扫频线性度较差,且会附加较大的调谐噪声。该结果为激光器扫频机制及控制技术的研究和工程应用光源选型提供了参考。

Abstract

We experimentally compare the detailed dynamic noise characteristics of a narrow linewidth-swept laser using different tuning mechanisms from three aspects, including the tunable frequency function in the time domain, frequency fluctuation power spectral density in the frequency domain, and its evolution law with time. All the analyses are conducted based on 120° phase difference interferometry and phase real-time reconstruction. The experimental results denote that different frequency-sweeping mechanisms and control parameters exhibit different real-time dynamic noise characteristics. Electro-optic modulation can obtain optimal sweep linearity using an optical phase-locked loop; however, this will result in noise deterioration such as feedback resonance peaks. Simultaneously, the different control parameters applied to the same electro-optic modulator will result in different feedback resonance peak frequencies. Acousto-optic modulation exhibits minimal noise degradation, and piezoelectric modulation results in poor sweep linearity and large tuning noise. This study lays the foundation for the research of the laser-frequency-sweeping mechanism and control technology and the selection of a light source in engineering applications.
