The field of ultrashort pulse generation is very mature nowadays, according to Hanieh Fattahi, the leader of the ‘Femtosecond Fieldoscopy’ independent research group at the Max Planck Institute for the Science of Light. ‘We are capable of generating pulses with arbitrary shapes at high average- and peak power,’ she said.
On the other hand, said Fattahi, ‘frequency-comb spectroscopy and field-resolved spectroscopy are opening new eras in sensitive detection. These two advancements set the stage for not only exploring a new era of light-matter interaction at unprecedented sensitivity but also employing them for real-life applications like spectro-microscopy of soft matter or sensitive monitoring of atmospheric pollutants.’
She believes field-resolved detection at simultaneously higher sensitivity and bandwidth remains a challenge: ‘There have been many different field-resolved methodologies, suggested and developed over the last few years. However, they are limited in terms of bandwidth and sensitivity. A novel solution could change the state of the art.’
