Setting up the optical parametric amplifier (OPA). With this setup, we can produce tunable femtosecond pulses from the visible to the deep UV

Up and running

It looks better with the lights off

Here's a video of a liquid microjet used for experiments studying ultrafast processes in water. The jet comes from the top and is only about 50 micrometers in width. The ice crystal forming from the bottom of the chamber is due to contact with the surface. 

Here's a second video of a liquid microjet used for experiments studying ultrafast processes in water. The jet comes from the top and is only about 50 micrometers in width. We used an automated arm to stop ice crystal formation. Here, you can even see ice crystals from contacting the surface of the arm.

After the experiment at FLASH was up and running, we set up a makeshift ping pong table
