Continuously adjustable hollow beam for ultrafast laser fabrication of size-controllable nanoparticles
The focused vortex beam generates a hollow beam, which has been widely used for size-controlled nanoparticle formation on various materials. However, the size variation of the vortex beam is limited by the integral order of the 2π phase wrap, while the waste is caused by the large side lobe around t...
