International Efforts to Control the Spread of Avian Influenza (H5N1) Virus: Affected Countries' Responses
Pulsed laser deposition of Ga-La-S chalcogenide glass thin film optical waveguides
Thin film optical waveguides of the chalcogenide glass Ga-La-S have been deposited on substrates of CaF2 and microscope glass by the technique of pulsed laser deposition. The chalcogenide properties of photobleaching, photodoping, and photoinduced refractive index changes have been observed and preliminary experiments carried out. The refractive index and thickness of the layer were verified using a waveguide "dark mode" analysis technique
