Researchers from the University of Aveiro in Portugal and the School of Engineering at Porto Institute of Technology (ISEP) in Portugal reported a study on the influence of laser beam intensity distribution on the geometric shape and process stability of lock holes under green laser radiation. The relevant paper titled "Influence of Laser Beam Intensity Distribution on Keyhole Geometry and Process...
Credo Technology Group Holding Ltd announced today the launch of the industry's first Dove 800 850G digital signal processor IC, which has been optimized for linear receiving optical devices and is also known as semi retiming linear optical devices in the industry. In LRO transceivers or active optical cables, only the transmission path from the electrical input to the output of the optical path i...
Recently, the team led by Professor Lv Zhiwei and Professor Bai Zhenxu from Hebei University of Technology, in collaboration with Professor Richard Mildren from Macquarie University in Australia and Professor Takashige Omatsu from Chiba University in Japan, successfully achieved direct output of Raman vortex optical rotation with large wavelength extension in a diamond Raman laser oscillator. This...
For a long time, craftsmen have been fascinated by the bright red color produced by gold nanoparticles scattered in colored glass masterpieces. The quantum origin of this optical miracle has always been mysterious, until modern advances in nanoengineering and microscopy revealed the complexity of plasma resonance.Now, researchers are preparing to push nano plasma technology, which was once used fo...
In today's rapidly developing technological era, structured light laser technology has become an important tool in the fields of 3D measurement and image capture. The core of this technology lies in a magical device called Diffractive Optical Elements (DOE), which can precisely control and shape laser beams, creating various complex light patterns. But what exactly is DOE? How does it work? Let Ho...
