Estimates if population inversion for deep-UV transitions in Kr-like Y,Zr,Nb and211 Mo in a high-current reflex discharge

摘要

Kr-like ions are good candidates for FUV lasing since they can be produced in211u001eplasmas quite easily. We present results from a spectroscopic investigation of Y 211u001eIV emission from a high current density, cold cathode reflex discharge. The Y II 211u001eto Y V emission is recorded in the 200-3000 (angstrom) range using 211u001ephotometrically calibrated spectrometers, while the emission of trace aluminum
