| Abstract: | The properties of two photon induced fluorescence and up conversion lasing of three novel laser dyes, PSPI, DEASPI and HEASPI, have been experimentally investigated. The above dyes emitted strong two photon induced fluorescence centred at ～640 nm and up conversion lasing at ～620 nm when pumped with 1064 nm mode locked Nd∶YAG laser. The output/input characteristics of the up conversion lasing were measured, and a high up conversion lasing efficiency of 10.7 for DEASPI, 9.8% for PSPI, and 7.1% for HEASPI have been obtained. |
