Beskrivning av upphandlingen
KTH requires a nanosecond pulsed dye laser system for deep ultraviolet Resonance Enhanced Multiphoton Ionization (REMPI) laser spectroscopy of dilute samples of small molecules. The system must be flexible, robust, and powerful with narrow linewidth, broad tuneability, and stable wavelength scanning. It will be used for quantum-state-resolved detection of scattered molecules as part of a molecular beam surface scattering instrument. REMPI has been chosen as the detection method because the molecular ions created in the process can be detected with high efficiency. The multiphoton nature of REMPI and the low density of molecules in the experiment place strict constraints on the properties required of the laser system.
