The spectroscopic and lasing characteristics of a series of 308 nm pumped p-oligophenylenes with five or more phenyl rings have been studied. Quantitative comparisons of the absorption spectra of these dyes with numerous other dyes in this class of compounds can be made by defining a parameter, theta, as the sum of the number of phenyl rings and the number of ring-bridges. Statistically good linear regressions result from the correlations of molar extinction with theta and from wavelength of absorbance with the reciprocal of theta. We find that these correlations provide good predictive information in deciding which dyes to attempt to synthesize for testing. The lasing characteristics of the dyes studied show that these dyes are amongst the best dyes in this class of dyes. Some of these dyes have exceptionally long lifetimes coupled with acceptable conversion efficiencies.

New excimer-pumped laser dyes based on p-quaterphenyl are described and the associated performance parameters are presented. A discussion of the variations in the performance parameters found is made in terms of dye chemical structures. Most of the dyes studied are significantly better than the chosen reference dye BBQ. The best dye in the series (dye 3) is stabilized both by ring-alkylation and by ringbridging. The net effect is the production of a new dye with a lifetime ten times greater than that of the reference dye BBQ.

The Third

The photophysical properties and the first observation of UV laser generation of molecules based on 2-phenylbenzothiazole with electron-donating substituents at the 2′ and 4′ positions are reported. The high gain of the amplified spontaneous emission, good efficient laser output, and extreme photostability for this class of laser dyes make their practical application feasible when pumped by the third harmonic (355 nm) of the YAG laser.

Alternative Solvents

The performance characteristics of a series of new excimer pumped ultraviolet dyes are presented. Chemical structure modifications which influence dye performance are discussed. An evaluation of several alternative solvents shows that p-dioxane remains the solvent of choice based on dye performance. The influence of the cover gas in the dye circulator was examined and results are presented to show how dye performance can greatly depend on this factor.
