Nonlinear propagation of intense femtosecond laser pulses in bulk transparent media leads
to a specific propagation regime, termed femtosecond filamentation, which in turn produces …

Nonlinear propagation of intense femtosecond laser pulses in bulk transparent media
produces a wealth of physical effects, whose combined action leads to a specific …

We experimentally investigate filamentation and supercontinuum generation in a
birefringent medium (BBO crystal), in the self-focusing regime where intrinsic cubic …

Generation of a high spectral power supercontinuum (SC) is reported from controlled
multifilamentation of femtosecond pulses in fused silica. The use of a microlens array allows …

We demonstrate a new security feature for visual control of the authenticity of optical security
features—the change of the images when the optical element is turned by 180 degrees …

Characteristics and formation mechanism of filamentary plasma string induced by single
picosecond laser pulse in sapphire are studied experimentally and numerically. Relative …

We show that a simple diffractive phase element (DPE) can be used to manipulate at will the
positions and energy of multiple filaments generated in fused silica under femtosecond …

In this work we demonstrate the ability of the spatiotemporal characterization technique
STARFISH to retrieve the wavelength dependent wavefront of focused ultrashort laser …

We report on deterministic femtosecond multifilamentation in fused silica by encoding a
diffractive microlens array into a spatial light modulator. The efficiency and focal length of …

We report on the experimental observation of periodic modulation of the axial luminescence
intensity along the femtosecond filament track in sapphire and crystal quartz. The physical …
