Few-Cycle Mid-Infrared Pulses

Currently strong-field physics is shifting towards the use of mid-IR sources.

Chiral Molecules

Chiral molecules exist in two non-identical mirror image forms.

Manipulating helium nanodroplets

Molecules are aligned in the laboratory frame (fixed in space) using laser pulses.

Pump-Probe Spectroscopy

Photolysis of amino acids by femtosecond UV and IR pulses.

Optical Trap

Measuring of forces between hydrophobic surfaces.


Use of supercontinuum sources for spectroscopy.
