Controlling ultrafast laser writing in silica glass by pulse temporal contrast
Yuhao Lei, Huijun Wang, Gholamreza Shayeganrad +2
Control of laser writing in transparent dielectrics using temporal contrast of light pulses is demonstrated. Anisotropic nanopores in silica glass are produced by high-contrast of…

Efficient, self-phase matched, narrow-band, engineered shape, tunable high-order harmonic generation based on femtosecond dynamic grating
L. Mashhadi, G. Shayeganrad
The high-order harmonic generation (HHG), if phase matched, opens a unique way to produce coherent ultrafast extreme-UV (XUV) or soft x-ray light sources. Here we describe a robust…
