Optical beam
WebCombined structural, optical and morphological studies were carried out on Eu 2 O 3 doped PbF 2-TeO 2-B 2 O 3 glass samples, before and after being subjected to electron beam of energy 7.5 MeV. XRD confirmed the amorphous nature of the glasses even after 150 kGy electron beam irradiation.

WebAn optical vortex(also known as a photonic quantum vortex, screw dislocationor phase singularity) is a zero of an optical field; a point of zero intensity. The term is also used to describe a beam of light that has such a zero in it. The study of these phenomena is known as singular optics. Explanation[edit] WebThe spectrum of the combined beam is measured with an optical spectrum analyzer. The spectral interval uniformly distributes with 0.6 nm. In this work, only 32 wavelengths are acquired, and the numerical range of the combined wavelength is 18 nm, which changes from 1054.8 nm to 1072.8 nm. This result is obtained because we have used 32 channels ...
