Determination of harmonic noise components against the background of other types of laser noise
The problem of research the reasons for limiting and reducing the stability of characteristics of coherent optical radiation sources is considered. The Experimental data are obtained by devises for measurement of power and frequency instability of laser radiation. Influence of laser radiation noise on stability of its parameters is revealed. The research are conducted by autocorrelation function and Allan variance. Pink noise, interference noise and other types of noise are found. Causes of noises are roughness of lasers tube cathode, material of devises for cavity adjustment, antireflection coating application and so on.
