Supercontinuum (SC) generation from alkali antimony zinc borate glasses was investigated using a femtosecond laser. The optical bandgap values were determined for all the glass samples. An enhancement in the generated SC is seen from sodium-doped gla

Femtosecond laser pulse induced filamentation in atmosphere is susceptible to a number of input laser, focusing optics and medium characteristics. Filamentation of fs pulses in atmosphere is an intense propagation regime where the focusing geometry u

We present the spatial and temporal characterization of the copper (Cu) plasma produced by the femtosecond laser filaments. The filaments of various lengths and intensities were generated with the aid of three different focusing lenses. Further, the
A special class of hippocampal neurons broadly known as the spatial cells, whose subcategories include place cells, grid cells and head direction cells, are considered to be the building blocks of the brain’s map of the spatial world. We present a

We report an enhanced supercontinuum generation (SCG) from a rare-earth ( P r 3 + ) doped low bandgap zinc borate glass when excited with 60 fs pulses from a Ti-sapphire laser. The emission associated with the absorption bands due to P r 3 + doping (

The codependence of third harmonic and supercontinuum generation during fs filamentation is demonstrated while varying the chirp and polarization of the input pulse. Phase matching for Third Harmonic generation is observed to influence the superconti
