Resolving the build-up of femtosecond mode-locking with single-shot spectroscopy at 90 MHz frame rate
Mode-locked lasers have enabled some of the most precise measurements ever performed, from attosecond time-domain spectroscopy to metrology with frequency combs. However, such extreme precision belies the comp...

Silicon's time lens
How can we capture ultrafast optical signals in real time? A time lens is one possibility — able to image the temporal profile of a short optical signal, analogous to a conventional lens. Such a device has now...

Amplified wavelength–time transformation for real-time spectroscopy
Real-time spectroscopy provides invaluable information about the evolution of dynamical processes, especially non-repetitive phenomena. Unfortunately, the continuous acquisition of rapidly varying spectra repr...
