Study on the Two-photon Frequency Upconversion Property of Two New Organic Dyes
Two-photon absorpuion and frequency upconversion properties of CEASP-Ce and CEASPI dye solutions have been measured. The upconversion fluorescence was measured to be around 610 nm when the two dyes were pumped with 930 nm laser. A good directional, high efficiency, narrow spectral width amplified spontaneous emission(ASE)could been observed when the concentration of the dyes were increased. The output verse input efficiency of the two dyes was different, but the overall net upconversion of them pumped by 975 nm laser reached about 20%. A comparison was made between the two samples though their different parameters, a result can be concluded from the structure of two samples that Ce~3+ affects the process of ASE by enhancing the absorption cross section.
