| Abstract: | We study the femtosecond filamentation in a liquid amplifying medium, sulphorhodamine 640 in a methanol solvent. In the presence of population inversion, the energy of the filament increases while its diameter expands because of peak intensity clamping. PACS 42.25.Bs; 42.65.Jx; 42.65.Re; 42.65.Sf |
