We unveil the existence of stable high-order dissipative spatiotemporal stationary solitons (i.e., light bullets) and breathers in the externally driven multimode nonlinear systems with a three-dimensional confining parabolic potential. Specifically, we focus on the externally driven multimode Kerr cavities. We show that the potential is responsible for stabilization of these three-dimensional states, and that it dictates their rich internal structure.

We implemented the single-shot terahertz spectrometer using an echelon mirror coupled with the phase-offset electro-optic sampling method. The single-shot sensitivity of the terahertz waveform approaches 1 V/cm, which opens a new possibility of detecting terahertz waveforms from various irreversible phenomena. Spectroscopy under pulsed high-magnet, terahertz spectral line imaging, and the terahertz spectroscopy of laser ablation processes are demonstrated. Pulse-to-pulse detection of the terahertz waveforms could bring new information on the ultrafast dynamics of materials and material processing.

Photon Doppler velocimetry (PDV) is a widely used diagnostic for measuring extreme surface velocities. Due to limited electrical bandwidth, conventional PDV systems suffer from limited velocity dynamic range when measuring extreme phenomena in shock physics. Time lens PDV (TL-PDV) overcomes these limitations by temporally magnifying the Doppler shifted beat frequencies allowing for recording with lower bandwidth electronics. Here we experimentally demonstrate TL-PDV and show a 74 km/s velocity range using only 12.5 GHz electrical bandwidth and a temporal magnification factor of 7.6. Furthermore, we validate this system by measuring Laser-Driven Micro-Flyers (LDMF) traveling at approximately 1 km/s.

The detection of rapid dynamics in diverse physical systems is traditionally very difficult and strongly dominated by several noise contributions. Laser mode-locking, electron bunches in accelerators, and optical-triggered phases in materials are events that carry important information about the system from which they emerge. By detecting single-shot spectra with high repetition rates over long-time scales, new possibilities and applications to diagnose, control and tailor the spectral dynamics of lasers and electron beams in synchrotron and free-electron laser (FEL) accelerators open up. This contribution focuses on the latest developments of real-time, single-shot, high-repetition-rate detectors and data acquisition systems, with a special focus on emerging technologies and new possibilities in the diagnostics of rogue optical signals.
