A pulsed laser employing Ar+ ions at high currents and low pressures

There are several papers 1–5] on pulsed Ar⁺ lasers, but all the tests have been done at low current densities (100 A/cm²). We have used densities up to 15–20 kA/cm², the best pressure range being 8×10^–3 to 2×10^–2 mm Hg. The generation under these conditions has some features not seen under ordinary conditions.
