Abstract (German)

Das Verhalten von F2m Farbzentren in Lithiumfluorid unter sättigbarer Absorption wird mit Hilfe von Pikosekundenlaserpulsanregung untersucht (Wellenlänge 1054 nm, Pulsdauer 6 ps). Die Farbzentrenanzahldichte, der Grundzustandsabsorptionswirkungsquerschnitt und der Einphotonen-Excited-State-Absorptionswirkungsquerschnitt werden durch numerische Simulation der Energiedichte-abhängigen ...

Translation of the abstract (English)

The saturable absorption behaviour of F2m color centers in Lithiumfluorid is studied by picosecond laser pulse excitation (wavelength 1054 nm, duration 6 ps). The color center number density, the ground-state absorption cross-section and the single-photon excited-state absorption cross-section are determined by numerical fitting the energy density dependent energy transmission. A decrease of ...
