AI Article Synopsis
- The study focuses on how a 30 femtosecond laser pulse behaves as it travels through gas with varying pressure levels.
- It demonstrates that having the right gas density profile can greatly enhance the process of pulse self-compression through filamentation.
- With the best pressure gradient, the pulse duration can be shortened to just one optical cycle over a long distance, making it easier to use in further experiments.
Article Abstract
We calculate pulse self-compression of a 30 fs laser pulse traversing gas with different pressure gradients. We show that an appropriate density profile brings significant improvement to the self-compression by filamentation. Under an optimal pressure gradient, the pulse duration is reduced to the single optical cycle limit over a long distance, allowing easy extraction into an interaction chamber.

Article Synopsis
- Coherent dispersive wave emission plays a key role in soliton dynamics across various nonlinear optics platforms, but generating efficient, ultra-broad bandwidth waves has been challenging due to resonance limitations.
- This study reveals a new approach where the dispersive wave emission process is strongly coupled with the driving pulse's dynamics, leading to high-efficiency coherent dispersive wave generation in the ultraviolet range.
- The process also produces a temporally-delayed ultrashort pulse that overlaps with the dispersive wave, resulting in significant spectrum broadening, which is valuable for applications like time-resolved spectroscopy and ultrafast electron microscopy.

Here a mechanism for self-compression of laser pulses is presented, based on period density-modulated plasma. In this setup, two pump beams intersect at a small angle within the plasma. This interaction is facilitated by the ponderomotive ion mechanism, which causes a modulation in the density of plasma with long wavelengths and low amplitude.

High-order harmonic generation (HHG) arising from the nonperturbative interaction of intense light fields with matter constitutes a well-established tabletop source of coherent extreme-ultraviolet and soft X-ray radiation, which is typically emitted as attosecond pulse trains. However, ultrafast applications increasingly demand isolated attosecond pulses (IAPs), which offer great promise for advancing precision control of electron dynamics. Yet, the direct generation of IAPs typically requires the synthesis of near-single-cycle intense driving fields, which is technologically challenging.

We implement variational shortcuts to adiabaticity for optical pulse compression in an active nonlinear Kerr medium with distributed amplification and spatially varying dispersion and nonlinearity. Starting with the hyperbolic secant ansatz, we employ a variational approximation to systematically derive dynamical equations, establishing analytical relationships linking the amplitude, width, and chirp of the pulse. Through the inverse engineering approach, we manipulate the distributed gain/loss, nonlinearity and dispersion profiles to efficiently compress the optical pulse over a reduced distance with high fidelity.
