摘要: The lasing efficiencies and photochemical stabilities of laser dyes useful in the 710-1080-nm spectral region have been investigated using a Q -switched ruby pumping source. measured bleaching rates P defined as probability irreversible decomposition dye molecule per absorbed photon, varied from \leq 1 \times 10^{-5} to 3 10^{-4} for different dye-solvent combinations investigated. Broad-band (the ratios output radiation input) ranged 4 43 percent. Shifts wavelength tuning range with variations solvent, concentration, cavity geometry are reported.
