We demonstrate that femtosecond filaments can set up an extended and robust thermal
waveguide structure in air with a lifetime of several milliseconds, making possible the very …

Laser-induced filamentation in the mid-infrared gives rise to unique regimes of nonlinear
wave dynamics and reveals in many ways unusual nonlinear-optical properties of materials …

Broadband Coherent Anti-Stokes Raman Scattering (B-CARS) is a powerful label-free
nonlinear spectroscopy technique allowing one to measure the full vibrational spectrum of …

We study the propagation of intense, high repetition rate laser pulses of picosecond duration
at 1.03 µm central wavelength through air. Evidence of filamentation is obtained from …

We experimentally investigate the nonlinear optical pulse dynamics of ultrashort laser
pulses propagating in gas-filled hollow capillary fibers in different dispersion regimes, which …

We review recent developments in the field of femtosecond filamentation. In a first part, we
describe the physical effects contributing to induce filamentation during the propagation of …

The femtosecond laser filamentation is of significant interest due to its remarkable
characteristics, and determining the critical power of self-focusing is essential for the process …

Recent works on plasma channels produced during the propagation of ultrashort and
intense laser pulses in air demonstrated the guiding of electric discharges along the laser …

Noninvasive imaging of visual system components in vivo is critical for understanding the
causal mechanisms of retinal diseases and for develo** therapies for their treatment …

We report on measurements of both the critical power for self-focusing of a Ti: Sapphire 800
nm femtosecond laser and the peak intensity clamped inside a single filament in an ethanol …
