Pressure-dependent optical delay time measurements in a coaxial electron beam pumped Ar:Xe laser

Abstract

Optical delay times and pulse widths of five Ar:Xe laser lines have been measured as a function of the total gas pressure. Both the delay time and the pulse width appeared to be almost linearly dependent on the inverse gas pressure. For a total gas pressure of 14 bars the delay times were around 100 ns, at a total gas pressure of 1 bar the laser output typically appeared after 1–3 μs.
