Mid-infrared femtosecond laser pulse filamentation in hollow waveguides: a comparison of simulation methods

This work compares computational methods for laser pulse propagation in hollow waveguides filled with rare gases at high pressures, with applications in extreme nonlinear optics in the mid-infrared wavelength region. As the wavelength of light \lambda=2\pi/k increases with respect to the transverse size R of a leaky waveguide, the loss... Show more
