Acoustic Sensing Enhanced Fibre
YOSC-FsWFBG-N is based on the self-developed femtosecond laser
automatic micromachining system to prepare a weak grating array,
which is written on a fibre with thousands of weak reflectivity
gratings. Using femtosecond laser direct writing technology,
the center wavelength, reflectivity and other parameters can be
customized according to customer needs. Combined with special
coated optical fibres, it can be stably used in extremely harsh
environments.
