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…

A double-clad ytterbium-doped tapered fiber with circular birefringence as a gain medium for structured light
Iuliia Zalesskaia, Yuhao Lei, Peter G. Kazansky +3
Amplifying radially and azimuthally polarized beams is a significant challenge due to the instability of the complex beam shape and polarization in inhomogeneous environment. In th…
