TLDR
Results are presented that demonstrate that the light intensity of a good-cavity single-mode standing-wave dye laser can exhibit chaotic behavior, and that the chaos is probably due to the turbulent flow of dye within the dye cell.Abstract:
Experimental results are presented that demonstrate that the light intensity of a good-cavity single-mode standing-wave dye laser can exhibit chaotic behavior. The governing attractor is of dimensionality 6.5 and entropy 50 kbits/sec. An examination of the pump-laser beam before and after its interaction with the dye indicates that the chaos is probably due to the turbulent flow of dye within the dye cell. This interpretation is confirmed by the absence of chaos in two similar dye lasers that use a dye jet rather than a dye cell.read more

A narrowband single-mode dye laser
TL;DR: In this paper, the linewidth of a cw-single-mode tunable dye laser has been investigated and it was found that the linwidth is determined by microscopic velocity fluctuations of the turbulent flow within the dye cell of the laser and by fluctuations of pump power.
