Award-winning photo of the liquid jet

Adrian Buchmann achieved third place at the Optica 2023 Photo Contest. With his image, which "captures the intersection of engineering, physics and chemistry in the realm of optical-pump THz-probe spectroscopy", he got a place on the podium.

The image depicts the "liquid jet" [1] the Havenith Group at Ruhr-University Bochum has engineered specifically for employing optical pump THz probe spectroscopy on water. This setup involves a thin stream of water stimulated by a blue laser. The response of the water is then observed with THz radiation. The image captures the "water jet" upon interaction with the blue laser beam.


Several research papers have resulted from this experimental setup:
