Discharge pumped ZnI (599–606 nm) and CdI (653–662 nm) amplifiers

Abstract
Peak small-signal gain coefficients (γ0) of 2.0% cm−1 and 0.7% cm−1 have been obtained on the B→X bands of CdI (cadmium monoiodide) and ZnI, respectively, in a UV-preionized, high-temperature (650≲T≲710 K) transverse discharge. For CdI, γ0 is greater than 1% cm−1 over a 90-Å (653≤λ≤662 nm) spectral region.
