Quantum ghost imaging offers many advantages over classical imaging, including the ability
to probe an object with one wavelength and record the image with another, while low photon …

We developed a rapid and efficient method for generating laser outputs with arbitrary
shaped distributions and properties that are needed for a variety of applications. It is based …

Since the advent of optical orbital angular momentum (OAM), advances in the generation
and manipulation of OAM beams have continuously impacted on intriguing applications …

Here, we experimentally demonstrate a straightforward-to-implement scheme that enables
the rotating velocimetry of a noncooperative target at large deflection angles. This scheme is …

Featured Application This work presents great opportunities for the enhancement of THz
image contrast. Abstract In this paper, we propose a terahertz (THz) spiral spatial filtering …

In this paper, we investigate depolarization properties of a quartz double-wedge Cornu
depolarizer with respect to the generation of spatially unpolarized light in terms of on …

A rapid and efficient method for generating laser beams with controlled intensity, phase and
coherence distributions is presented. It is based on a degenerate cavity laser in which a …
