Reflection setup

We implemented the new capability of measuring TG signals in reflection! 

During the last months the TIMER team, in collaboration with the K. Nelson group at the MIT (BT. 20174120), the Giordano group at the Université Claude Bernard Lyon 1 (BT. 20184032) and the Baldi group at the Trento University (BT. 20184081), implemented the reflection setup. This setup, shown in the above picture, allows to detect the phase-matched back-scattered transient grating signal. This capability opens up the possibility of investigating opaque samples, previously not available at TIMER, as well as measuring both the reflected and transmitted signal in thin, transparent membranes.
