Liquid samples

To minimize scattering and pulse elongation, we circulate our liquid samples in a window-free wire-guided jet. A stable film of approximately 200 μm thickness forms between the two wires. The bright spot is the focus of our three excitation beams. We can use solvents with high surface tension such as water or benzonitrile.

Diffractive Optical Element

Non collinear parametric amplifier
