In ultrafast optics, it often proves invaluable to exactly know the temporal structure of the few-cycle pulses in the experiments. Compared to transient events in electronics, our means of precisely measuring optical transients on the femtosecond scale appear much more limited. To this end, a number of techniques have emerged that enable simultaneous measurement of the amplitude and phase structures of ultrashort pulses. Among these techniques, interferometric frequency-resolved optical gating has evolved as a particularly powerful technique, which can also be used for spectroscopic experiments on the few-cycle temporal scale.

Experimental setup for filament generation in a controlled noble-gas atmosphere. The characteristic sign for the onset of plasma formation and filamentation is the color change from red (scattered light) to violet (fluorescence) appearing at the 7 cm position on the ruler. After the collapse of the filamention process at 70 cm, a white-light spectrum emerges. Spectral width and the number of filaments inside the cell can be controlled by pressure and gas fill.

A second important aspect is measurement and control of the carrier-envelope phase of an ultrashort optical pulse. This phase plays an important role in attosecond spectroscopy. We have developed the feed-forward technique for stabilization of the carrier-envelope phase. This patented method is now commercially available from a major laser manufacturer. Our research continues and tries to explore the absolute limits of carrier-envelope phase measurements, as they are, e.g., imposed by quantum noise mechanisms.

Further research is devoted to optical filamentation. Loosely focusing an intense laser beam in air, one observes a collapse of the beam profile, and a plasma channel forms that guides the light at nearly constant beam diameter for lengths in the centimeter or meter range. Further increasing the laser power, several such filaments coexist parallel to each other and show highly dynamic behavior. The resulting beam profiles exhibit short-lived extremely bright flashes, which appear in analogy to ocean rogue waves. We carefully studied the statistics of rogue waves in our multifilament scenario and compared them to other rogue-wave supporting systems. This comparison seems to enable some intriguing new insight into the ocean rogue wave mystery, which we are currently exploring in more depth.
