“…The line focus generates a single column of filaments. We studied the filamentation process using Femtosecond Time-resolved Optical Polarigraphy (FTOP) [30]. This technique uses the transient birefringence induced in the material through the Kerr effect to capture the beam profile.…”

Abstract:We present experimental results on the transverse modulation instability of an elliptical beam propagating in a bulk nonlinear Kerr medium, and the formation and self-organization of spatial solitons. We have observed the emergence of order, self organization and a transition to an unstable state. Order emerges through the formation of spatial solitons in a periodic array. If the initial period of the array is unstable the solitons will tend to self-organize into a larger (more stable) period. Finally the system transitions to a disordered state where most of the solitons disappear and the beam profile becomes unstable to small changes in the input energy.

“…Femtosecond time-resolved optical polarigraphy can be used to observe nonlinear index changes induced through the Kerr effect. 11,12 This technique captures the transient birefringence induced in the medium, but does not capture isotropic index changes. We have previously demonstrated a holographic technique 13 that captures laser-induced plasma formation with 150 fs time resolution and recovers amplitude and phase information with a spatial resolution of 4 m. Laser pulses with duration of 150 fs probe the changes in the material properties induced by a high energy pump pulse.…”

We have implemented a holographic system to study the propagation of femtosecond laser pulses with high temporal ͑150 fs͒ and spatial resolutions ͑4 m͒. The phase information in the holograms allows us to reconstruct both positive and negative index changes due to the Kerr nonlinearity ͑positive͒ and plasma formation ͑negative͒, and to reconstruct three-dimensional structure. Dramatic differences were observed in the interaction of focused femtosecond pulses with air, water, and carbon disulfide. The air becomes ionized in the focal region, while in water long plasma filaments appear before the light reaches a tight focus. In contrast, in carbon disulfide the optical beam breaks up into multiple filaments but no plasma is measured. We explain these different propagation regimes in terms of the different nonlinear material properties.

“…In these researches, however, only the relation between the time evolution and other physical quantity, such as energy to time, is discussed. On the other hand, the researches which pursue the space propagation [15,16,17], those which pursue time evolution of the intensity accompanying propagation of femtosecond laser light [18,19] have been carried out, but these researches require not only repetitive femtosecond pulses but also the images are temporally discrete and consist of a few or several frames. Therefore, these researches are quite difficult to apply in the case that the property of each pulse is inhomogeneous among the repetitive pulses.…”

Abstract:We have developed an ultrafast imaging system to record and observe the femtosecond phenomena in air and an optical medium as a form of a temporally continuous motion picture. To obtain the motion picture, the light-in-flight recording by holography using a femtosecond pulsed laser is applied. We demonstrate the recording and observation of femtosecond laser pulse propagating in air and a dispersion prism. The time and spatial behavior of such femtoseconed light pulse in the prism and at the boundary between the prism and air is clearly observed. This technology achieves a temporal microscope with more than 10 11 magnification.
