We consider sharp focusing of an axial superposition of two optical vortices with identical topological charges, but different amplitudes and circular polarizations of different signs. The ratio of the amplitudes of the two beams is a parameter. When thi...

The one-dimensional, high-order Hermite?Gaussian (HG0n) laser beams can be easily converted into vortex Laguerre?Gaussian (LGpl) beams carrying orbital angular momentum (OAM), and with the scaling of output power and the narrowing of pulse width, the app...

Obtaining the inertia tensors of defunct space objects is essential in on-orbit missions. When the inertia tensor of the space object is non-diagonal, the problem becomes challenging. In this case, the system does not have enough information to estimate ...
