High Pulse-Energy Flashlamp-Pumpable Laser Dyes

摘要

To obtain higher pulse energies from laser dyes by means of flashlamp pumping insolution, several new prototype dyes were synthesized and submitted to MICOM for testing. The dyes were intended to display high pulse energy either in a flowing solution in a non flammable solvent or in the solid poly (methyl methacrylate). The class of laser dye known as 4PyMPO was given an expanded fluorophor by substitution of a biphenylene for the phenylene (P) group. None of the expected increases in extinction coefficient (e), fluorescence quantum yield and emission wavelength were obtained.
