Co spinel——saturable absorbers for the passive Q-switching of solid-state lasers operating at eye-safe wavelength of 1.5 μm Cobalt-doped magnesium aluminate spinel (Co:MgAl2O4) allow the generation of ...
BIOLOGICAL materials consisting largely of protein and carbohydrate give rise to infra-red absorption spectra which show the main characteristic absorption bands of the protein and carbohydrate ...
