Controlling the Waveform of Ultrashort Infrared Pulses

3 Jun 2022

An international team of laser physicists of the attoworld team at LMU and the Max Planck Institute of Quantum Optics has achieved unprecedented control over light pulses in the mid-infrared wavelength range.

Ultrashort infrared light pulses are the key to a wide range of technological applications. The oscillating infrared light field can excite molecules in a sample to vibrate at specific frequencies, or drive ultrafast electric currents in semiconductors. Anyone intending to exploit the oscillating waveform of ultrashort light pulses, to drive cutting-edge electro-optical processes for example, faces the same question — how to best control the waveform themselves. The generation of ultrashort pulses with adjustable waveforms has been demonstrated in different wavelength ranges like the UV-visible and the near-infrared.
