“…Furthermore, each of these ranges, except the 12 emission, would probably consist of a series of peaks, attributable to the constituent vibrational levels where the gain would be the greatest at the optimum overlap of rovibronic transitions centred approximately 3.5 nm apart. Confirmation of this result has been given recently in a broad-band optically pumped, triple mercury halide laser by Bazhulin et a1 (1986).…”

A spectroscopic study has been made on various mixtures of the mercurous halides HgX(X=F, Cl, Br, l) photodissociated from the mercuric salts by ArF excimer laser excitation at 193 nm. The combination of two or more different halides of mercury within a laser cavity, operating under similar conditions to the single HgX lasers, is a logical step forward in extending the tuning range within the visible spectrum. The effect of such mixtures upon the laser absorption bands for both photolytically pumped and electrically excited laser emission and the production of interhalogen compounds and their effect on laser emission is discussed. For certain mixtures, a continuous fluorescence emission band was observed from 420 nm to 560 nm with further emission at 340 nm. It was deduced that mixed laser emission would occur in four bands: 340 to 343 nm, 440 to 445 nm, 493 to 510 nm and 533 to 565 nm; this has been confirmed by recent laser measurements.

“…The more efficient utilisation of the emission spectrum of a wideband optical pump source has recently been confirmed by Bazhulin et a1 (1986). Another advantage in the successful combination of the mercury halides would be the creation of a high-energy efficient wide-band laser source tunable across the constituent HgX laser spectra providing an alternative to tunable, pulsed dye lasers with the added advantages of a longer lifetime and wider tuning range.…”

The authors report the first study of reaction mechanisms on optically pumped vapour mixtures of HgX2 (X=F, CI, Br and I) using ArF excimer laser excitation at 193 nm. Chemical and photolytically induced reactions take place yielding new species such as mercury interhalide complexes (HgXX'), interhalogens (XX'), dimers (Hg2X2), 'heavy' mercury (II) interhalogen complex dimers (Hg2XX'), as well as free mercury (Hg) and halogens (X2). The effects of such mixtures upon the laser absorption and emission bands for both photolytically pumped and electronically excited laser emission and the production of interhalogen compounds and their effect on laser emission is discussed.
