Recently it has been shown that one can convert a vector beam in frequency while retaining the polarisation structure, but changing wavelength207,208,209, for faithful vectorial wavelength control. A recent development is the use of structured matter for non-linear control of structured light. ...

In our experiments, the excitation beam and the fluorescence signal could reach the camera directly without being scattered. However, in most biological settings, the detection path will not be clear and the signal coming from the sample plane will be aberrated and scattered as well. This would ...
Therefore, the vector light field generation method based on an SLM is widely used. For example, Ding’s research group [23] divided the incident beam into two beams from a computer-generated hologram (CGH) written to the SLM. Each beam is encoded using the specified complex field, and ...
Here, light emitted by a two-dimensional object, such as a fluorescent sample, propagates towards a lens whose focal length is 𝑓=100mmf=100mm; after the lens, the light beam is split towards two detectors 𝐷𝐴DA and 𝐷𝐵DB, endowed with spatial resolution. The two lens-detector...
printed microparticles for potential pharmaceutical applications. The critical high-quality micro-optical components of the setup, namely a diffractive optical element generating the 7 × 7 beamlets and a 7 × 7 lens array, are manufactured by using a commercial two-photon grayscale 3D laser ...
Through modulating the Bessel-Gaussian radially polarized vector beam by the cosine synthesized filter under a reflection paraboloid mirror system with maximum focusing semi-angle of π/2, arbitrary-length super-Gaussian optical needles are created with consistent beam size of 0.36λ (full width at ha...
