This paper includes a preliminary study of bringing innovative and promising distributed optical fiber sensing technologies to strain monitoring of hydraulic machinery. ...
We demonstrate an active random fiber laser by directly pumping a 100 m erbium-doped fiber at 980 nm wavelength, with a fiber loop mirror forming a half-open cavity. Random lasing with competing spectral modes in the range from 1535 nm to 1560 nm is achiev ...
This paper demonstrates the feasibility and huge potential of applying distributed fiber optic sensing technologies to strain monitoring and failure predictions in hydraulic machinery, validated by a good match between experimental results and theoretical ...
The effect of Rayleigh scattering enhancement in an optical fiber on the random fiber laser efficiency is investigated, and the effect of different corresponding fiber loss is also studied. ...

A random Q-switched Erbium fiber laser is obtained with an average repetition rate to several kilohertz, and its output spectrum can be easily flipped from 1535 to 1550 nm by a fiber loop mirror. ...
