In order to successfully 3D print metal parts to meet the strict specifications required by many industries, it is necessary to optimize process parameters, including printing speed, laser power, and layer thickness of deposited materials.However, in order to develop additive manufacturing process diagrams that ensure these optimal results, researchers have to rely on traditional methods, such as ...
Recently, optical semiconductor developer Lumiotive, headquartered in Seattle, USA, launched a new LiDAR sensor LM10, which is its first fully produced product of light controlled metasurface (LCM) technology designed for digital beam steering.The developers stated that compared to mechanical systems, their digital beam steering method overcomes the limitations of traditional LiDAR sensors in term...

The first-order diffraction beam of B displays a colorful rainbow pattern from purple to red.d. The HCF-LN-CPPLN module generates normalized spectra of the output full spectrum laser signal through the second NL HHG and third NL SPM e...
A powerful telescope in South Africa has detected a space laser 5 billion light-years away from Earth, known as the "megamaser". Scientists named it Nkalakatha, which means "big boss" in Zulu language.Nkalakatha is the farthest hydroxyl giant detected so far, discovered by the MeerKAT telescope on the first night of the survey, which is expected to include 3000 hours of observation. The team of sc...
The deformable mirror used in adaptive optics can instantly correct the static wavefront aberrations and atmospheric turbulence wavefront disturbances of the optical system by changing its surface. This enables the optical system to automatically adapt to changes in the environment and maintain optimal performance. It is widely used in high-resolution astronomical observations, laser atmospheric t...
