A novel z‐scanning‐free epi‐detected super‐resolution two‐photon fluorescence tomography (TPFT) technique enabling super‐resolution deeper tissue 3D imaging is reported. To accomplish this, a unique method is conceived by generating the phase‐shifted optical beatings of Bessel beams (PS‐OB3) with a spatial light modulator (SLM) to break the diffraction limit for enhancing both the lateral and axial...
Engineering the polarization and spatial phase of ultrafast laser pulses represents a compelling strategy for enhancing control over laser–matter interaction and enabling rapid and innovative nano‐fabrication processes. Here, the single‐shot, ultrafast laser fabrication of high‐aspect‐ratio, vertically standing nano‐pillars with a diameter of nm and height up to 15 µm on the surface...
