Abstract
The temporal and spectral properties of two-photon induced fluorescence and up-conversion lasing of two new laser dyes have been experimentally invest igated. Pumped by 1064 nm mode-locked Nd:YAG laser, effective two-photon in duced fluorescence with peak wavelength at 635 nm and up-conversion lasing at similar to 626 nm emitted from the solutions of these new dyes in DMF. T he lifetimes of two-photon up-conversion fluorescence of the two dyes are 6 5 and 67 ps. At picosecond laser pumping, the efficiency of up-conversion l asing is 8.4% and 9.1% for the two new dyes.
