GETTING MY CO²�?/ZNS CRYSTAL TO WORK

Fabrication and characterization of mid-infrared emission of Pr 3+ doped selenide chalcogenide glasses and fibresPeriodic Q-switched twin-wavelength oscillation regime is suggested and modeled working with Er:YAG laser with Co:ZnSe passive Q-switcher with lasing switching in the vicinity of 1645 and 1617 nm as an example for methane remote sensing.
