Dichroism upon laser-induced fragmentation of small (chiral) molecules (A10*)

• Subject Area: Optics, Quantum Optics and Physics of Atoms, Molecules and Plasmas
• Term: since 2026
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 328961117

We study the fragmentation and ionization of chiral molecules in the strong-field, long-wavelength regime of tunnel ionization using femtosecond laser pulses and tailored pump-probe schemes. We measure three-dimensional momentum distributions of electrons in coincidence with fragment ions using a COLTRIMS Reaction Microscope. Further, we also have the ability to detect neutral fragments that are created by the pump pulse because our probe pulse can ionize them to render them detectable as charged particles.
