Application of surface science techniques to study a gilded Egyptian funerary mask: A multi-analytical approach
(John Wiley & Sons Ltd, 2019-10)
A wide range of analytical techniques has been used to study an Egyptian funerary mask of the Ptolemaic period (305-30 bc). Secondary electron (SE) and back-scattering (BS) images, recorded by a scanning electron microscope ...
Erbium ring fiber laser cavity based on tip modal interferometer and its tunable multi-wavelength response for refractive index and temperature
(Multidisciplinary Digital Publishing Institute (MDPI), 2018-08-10)
A tunable multi-wavelength fiber laser is proposed and demonstrated based on two main elements: an erbium-doped fiber ring cavity and compact intermodal fiber structure. The modal fiber interferometer is fabricated using ...
