Spectroscopy

In time-resolved measurements, an ultrafast pulse triggers a reaction and a second pulsetakes a snapshot of the induced change. By shifting the arrival time of the probe pulse withrespect to the pump pulse the stimulated process
can be followedin time.

Optical Sampling Engine
COMPLETE SOLUTION:
The turn-key, fully hands-off optical setup is integrated into a 19” 3U rack, and offers unprecedented compactness. The embedded platform
ensures automatic laser stabilization. Changes of the operation mode can be done through the front screen, or be remote control over network
by a browser-based graphical user interface. For convenience, the system offers a TTL trigger signal. Additionally, the OSE can provide additional outputs as a seed to pump external amplifiers.
