Description

This laser set-up is dedicated to ultrafast experiments on (bio-) molecular systems in the condensed phase. It consists of an amplified 1 kHz/5 kHz Ti:sapphire system with frequency conversion schemes from the near-UV via VIS and NIR to mid-IR, with detection equipment dedicated for femtosecond mid-IR pump-probe and photon echo experiments.

For more details on equipment see:
