TL;DR: In this article, a tunable dye laser was described, which was pumped by 300 ps pulses from a travelling wave N 2 -laser due to the short resonator length pulses with only 50 ps duration are emitted.

TL;DR: Bile pigments show a certain chemical relationship to haem and chlorophyll, but the pyrrol rings do not form a closed porphyrine ring like in these molecules.
Abstract: Bile pigments are biological dyes built up essentially of four pyrrol rings. Thus they show a certain chemical relationship to haem and chlorophyll, but the pyrrol rings do not form a closed porphyrine ring like in these molecules. Bile pigments are found in various biological systems (e.g. mammalian liver and bile, bird egg-shells, insect wings and cuticula pigments, red and blue algae, higher plants). They play a key role in a number of important photochemical processes, namely
1)
photo therapy of hepatitis in new-born babies
2)
photosynthesis in red and blue algae
3)
higher plant morphogenesis.
