Abstract

Cool et al.¹ have suggested that laser emission from the atomic Hg analogous to that observed in the photodissociation of Hg₂ (Ref. 2) should be possible by using mercury halides. Recently we observed very strong superradiation at 4046.6 Å (7³S₁ → 6³P₀) and 4358.3 Å (7³S₁ → 6³P₁) from atomic Hg produced by photodissociation of HgBr₂ with an ArF sxcimer laser at 193 nm. The spectrogram of laser emission from mercury atoms was shown in Fig. 1.
