We experimentally demonstrate that 2D Airy wave packets can produce intense curved two-color filaments that emit terahertz (THz) radiation with unique characteristics. Due to the curvature of the plasma channel, THz waves, emitted from different long

Tornado waves (ToWs) [1] were recently introduced theoretically as a new type of structured light that twists and accelerate both over the radial and the angular dimensions. Tornado waves are comprised by superimposing cylindrically symmetric acceler

Two-color laser filamentation constitute one of the most convenient and efficient sources of pulsed ultra-broadband terahertz (THz) radiation. In this approach, a Gaussian ultrashort laser pulse together with its second harmonic are focused into a ga

We report on THz generation from curved filaments produced by 2D Airy wave packets. Due to the curvature of the plasma channel, non-concentric THz beams with different polarizations are generated.

We experimentally generate Tornado Waves using a single phase modulation device. We show that, by applying spatial multiplexing techniques, such complex superimposing fields that carry orbital angular momentum of opposite handedness can be efficientl

Generation of ultra-broadband beams with a non-trivial wave-front is a major challenge [1,2]. Such beams are of interest in many fields ranging from bio-medical applications to materials processing and optical telecommunications. Recently a novel typ

In laser material processing optical wave packets are used as means to efficiently deliver energy on a remote target. The scalability both in power and focal dimensions is an important problem in such applications. For example, higher powers ignite n

We show that through the use of optical aberrations, a reflective cylindrical beam expander can be properly adjusted to perform as a tunable ultra-broadband continuous phase modulation device. We demonstrate the effectiveness of such a device for the
