Abstract :
A series of new organic molecules with high efficiency for two-photon-pumped lasing have been synthesized in this work. Ultrafast spectroscopy demonstrates very fast emission dynamics in this kind of compound, which is an important characteristic for their application. It results in an efficiency of upconverted amplified spontaneous emission (ASE) up to 12.6% at the pumping of a picosecond laser.
