Abstract :
The lasing efficiencies and photochemical stabilities of laser dyes useful in the 710-1080-nm spectral region have been investigated using a 
-switched ruby laser pumping source. The measured bleaching rates 
defined as the probability of irreversible decomposition of a dye molecule per absorbed photon, varied from 
to 
for the different dye-solvent combinations investigated. Broad-band lasing efficiencies (the ratios of dye laser output to ruby radiation input) ranged from 4 to 43 percent. Shifts of wavelength tuning range with variations in solvent, dye concentration, and dye laser cavity geometry are reported.
