Our aim is to achieve lasing at 13.38 nm wavelength, using excited hydrogen-like nitrogen ions (N6+)*. The primary pumping process is a three-body collisional recombination, taking place in a non-stationary under-cooled plasma created during the pinch expansion stage. To design optimum parameters of the device we have performed computer modeling for various capillary radii and current pulse shapes,...
Summary form only given. Pinching capillary discharge in nitrogen is investigated for the purpose of laser recombination pumping. An apparatus, previously realized for argon capillary laser, was used to understand details of pinching mechanism and emission characteristics. The experiments were done with alumina capillary (297 mm long, inner diameter 3.2 mm) filled by nitrogen (pressure 0.1-10 torr)...
