Prof. Jalali’s work in collaboration with U. Gottingen in Germany appeared on the cover of Nature Photonics-5/2016.

The cover shows the first ever observation of mode locking dynamics inside the femtosecond laser as it occurs in real-time. The feat was enabled by Photonic Time Stretch technology pioneered in Jalali-Lab. Such lasers are the gold standard in time and frequency standards and the workhorse of precision measurements.
