NOT KNOWN FACTUAL STATEMENTS ABOUT CO²�?/ZNS CRYSTAL

In this particular paper, we report the preparing and Qualities of a novel chalcogenide photonic crystal fiber that has a high extinction ratio (ER). The GePeriodic Q-switched twin-wavelength oscillation regime is proposed and modeled employing Er:YAG laser with Co:ZnSe passive Q-switcher with lasing switching close to 1645 and 1617 nm for example
