Direct Generation of Tunable Femtosecond Vortex Arrays in a Yb:CALGO Laser

A novel method for directly generating ultrafast vortex arrays within the cavity of a femtosecond Yb:CALGO laser oscillator, based on transverse mode locking, is proposed and experimentally demonstrated. This approach achieves dual‐degree‐of‐freedom active control over the topological structure of vortex arrays withi...

Scattering-force-driven light-sheet fluorescence microscopy for scan-free three-dimensional imaging

Optical manipulation offers a powerful non-contact approach to precise positioning, directional transport and three-dimensional (3D) imaging of microscale objects. However, positional fluctuations during optical confinement introduce spatial sampling errors that compromise imaging quality and acquisition speed. Here, w...
