A new laser source for the analysis of molecular fingerprints

February 14, 2020

publications – Controlling, shaping, and measuring the electric field of light at sub-cycle regime enhances the depth of our insight into microscopic ultrafast dynamics at femtosecond and attosecond time scale. Our developed laser architecture fulfills these criteria.

On the one hand, the system allows to generate optimized, non-sinusoidal pulses with scalable peak and average-power for attosecond pulse generation.

On the other hand, the system enabled us to detect the electric field of the absorbed light by water molecules at near infrared spectral range for the first time. The demonstrated control and measurement of the electric field of light at petahertz holds promise to open up new opportunities for precise observation and control of molecular vibrations over the entire molecular fingerprint region down to a few femtosecond time scales.
