By enabling Free Space Optics (FSO) technology as complementary solution to RF systems, the next generation satellite communication that relies on optical links is on the verge. Even though the transition to wireless optical communication is a fact, the space domain is very conservative to such critical changes that call for close evaluation of each system aspect. Since trade-off between costs and efficiency is required, a state-of-the-art laboratory testbed for verification of satellite-to-grou...

Volume density gratings produced by degenerate, counterpropagating laser pulses in plasma have several useful optical properties. Here we report on one of these in an investigation into creation of a transient plasma density grating that functions as a waveplate.

The accelerating structure of the laser wakefield accelerator (LWFA) is dynamic and highly sensitive to the local laser and plasma properties. It can expand and contract as it responds to the evolution of the laser and plasma fields. As a result, the position of, and environment within, the LWFA bubble are usually time dependent, which is not ideal for stable acceleration. Variations can have a negative impact on electron bunch properties, and are deleterious for ion channel lasers and plasma wi...

The powerful discipline of optogenetics can be described as “the branch of biotechnology which combines genetic engineering with optics to observe and control the function of genetically targeted groups of cells with light”. Using advanced laser beam-shaping such as Generalized Phase Contrast (GPC) and derived holographic modalities makes it possible to take advantage of cutting-edge two-photon technology to develop an unprecedented ‘circuit optogenetics’ platform with both high spatio-temporal ...

Diffuse correlation spectroscopy (DCS) is an optical technique which, by studying the speckle intensity fluctuations of coherent light diffused in a turbid medium, retrieves information regarding the scatterers motion. In the case of biological tissues, the particles of interest are the red blood cells, from which is possible to measure non-invasively microvascular blood flow (BF). However, being based on a continuous-wave light source, depth discrimination is achievable only by using multiple s...

Tissue polarimetry could be identified as a complementary optical and non-invasive technique to assist the gold standard histopathology analysis of tissue. In general, polarimetric diagnostics is based on tracing different polarimetric responses (including light depolarization) in tissue zones with structure altered by the benign and pre/cancerous formations. In this manuscript, both healthy and malignant tissue zones of a thick formalin-fixed colon specimen were used for Mueller matrix measurem...
