We numerically investigate the nonlinear propagation of long-wavelength, higher order Bessel pulses in the atmosphere. We show that 10 micron higher order Bessel beams can generate more homogeneous plasma channels than their 800 nm counterparts. We u

Long-wave multi-joule ultrashort laser pulses are predicted to confine highly uniform electromagnetic energy and field intensities while sustaining high density uniform plasmas within nonlinear Bessel zones under extreme driving conditions in contras

Pulse self-compression is demonstrated numerically for 10.3 µm pulses in a gas-filled multi-pass cell. The cell is filled with the 13CO2 isotope, which exhibits a shifted absorption spectrum from the 12CO2 laser gain medium.

We simulate the linear and nonlinear propagation dynamics of multi-TW 10.6 μm square-frame wavepackets in the atmosphere. It is shown that the location of the obscuration is critical for multiple-filamentation and energy delivery downstream.

We study the interplay between three-dimensional (3D) fully correlated optical turbulence and nonlinearity in time and 3D space resolved long-wavelength infrared pulsed beam propagation. Here the average self-trapped beam waist exceeds the inner scal

The diffraction-compensated propagation of high-power laser beams in air could open up new opportunities for atmospheric applications such as remote stand-off detection, long-range projection of high-energy laser pulses and free-space communications.

A gas-filled multi-pass cell is modeled to self-compress a 10 µm pulse to sub-100 fs duration while containing multi-terawatts of peak power. The motivation for modeling a source with the demonstrated power is for use in laser wakefield accelerators

We investigate the atmospheric propagation of high power 10μm — picosecond laser pulses over multi-km distances in the atmosphere. We predict that 10μm atmospheric filaments have noteworthy advantages when compared their shorter wavelengths count
