Time-of-flight mass spectroscopy of femtosecond and nanosecond laser ablated TeO2 crystals

▶ Single-pulse fs and ns-laser ablation of single-crystalline TeO2. ▶ Significant differences observed regarding the laser-induced species in the plasma plume. ▶ Singly charged positive Te ions in the form of six isotopes were detected predominantly in the ablation plume in case of both ns and fs-laser irradiations. ▶ The Te ion peak intensities in the TOFMS strongly depended on the applied laser pulse energy.
