QuickShape IR Mid-IR Pulse Shaper System
Aarhus University wants to purchase a QuickShape IR Mid-IR Pulse Shaper. It will be used to investigate molecular coupling and dynamics at interfaces. The devise will be integrated into an existing laser setup to provide high power ultrashort laser pulses in the mid IR spectral region. The QuickShape IR Mid-IR Pulse Shaper is he only device on the market with the ability to control the phase and shape of high power mid IR laser pulses.
The customer is an associate professor at the Chemistry Department of Aarhus University and head of the surface spectroscopy facility SurfLab. We intend to purchase a pulse shaper system for a planned research project.
Reactions, chemical composition and structure at interfaces are usually markedly different from those of the bulk materials. The properties of a material surface determine its performance in a given application. Typical examples include catalysis, nucleation, sensing, wetting, target binding, and biocompatibility. However, relative to bulk materials, it is extremely challenging to obtain information at ultrafast timescales about surface structure, molecular motion and energy transfer. Two-dimensional surface spectroscopy can provide this information and has proven to be a reliable tool to probe ultrafast surface processes. For a 2D experiment it is required to prepare trains of femtosecond laser pulses in the mid-IR region with exquisite control of temporal spacing, relative phase and spectral shape. The pulse must have average powers of several micro Joule, which means the pulse shaper must be optically pumped with 10-100 uJoule of average power.
The customer has performed a systematic search for commercially available pulse shapers. The QuickShape IR Mid-IR Pulse Shaper is the only high-power mid-IR pulse shaper available on the market offering the pulse control needed for the experiments. This provides us with extremely high performance laser pulses which allows us to visualize molecular reactions, motions and energy transfer at interfaces with unprecedented detail.
