Abstract

Transient absorption spectroscopy has been used to examine the active region of an ultraviolet-preionized, discharge pumped cadmium monoiodide (114CdI) laser. Having an active length of 50 cm and a gas mixture composed of He, N2 and 114CdI2 vapor, the discharge was probed by a short pulse (∼0.6 μs) Xe lamp in conjunction with an optical multichannel analyzer. In addition to the 53P → 63S1 lines of Cd, CdH molecules were observed in absorption (X2Σ → A2Π) but not in emission. Also, a broad band exhibiting distinct undulatory structure and peaking near 454 nm is reported and tentatively attributed to CdI.
