Abstract

The production of picosecond pulses in the blue region of the spectrum [1,2] has stimulated our interest in methods of amplifying such pulses. The photophysics and photochemistry of stil-bene laser dyes have not previously been studied by picosecond spectroscopy. We report the gain kinetics and spectra of all trans-1,4-Bis(2-methylstyryl)benzene (Bis-MSB). This laser dye apparently undergoes very little excited-state conversion to a cis-form. Indeed, in related molecules the all trans-form is favored by photoisomerization [3]. Recently, picosecond kinetics of photoisomerization in cis- and trans-stilbene were reported [4]. The gain kinetics reported in this paper are discussed in terms of the excited state conformation, vibrational level, orientation, and population.
