OLED is located at the top and is formed by an organic layer between the contacts. Apply voltage to it, inject charge and generate light, which in turn excites organic laser. Organic lasers contain a grating that can generate feedback and diffract some of the laser out of the structure.Organic laserResearchers have created the first organic semiconductor laser to operate without the need for a sep...
Liquid crystal elastomers are expected to be applied in displays, sensors, smart devices, and wearable devices.A team from POSTECH University in South Korea, led by Professor Su Seok Choi and Professor Seungmin Nam, has developed a new type of stretchable photonic device that can control the wavelength of light in various directions.This work was carried out by the Department of Electrical Enginee...
Researchers at the University of Sydney combined photon filters and modulators on a single chip, enabling them to accurately detect signals on the broadband RF spectrum. This work brings photonic chips closer to one day, potentially replacing larger and more complex electronic RF chips in fiber optic networks.The Sydney team utilized stimulated Brillouin scattering technology, which involves conve...
Laserline will once again showcase its latest laser systems for joining and deposition welding at this year's Welding & Cutting show in Hall 5. This time the focus is on the world's first blue diode laser with an output power of 4 kW, which is said to have been developed for processing copper components.Its 445 nanometer wavelength is absorbed by copper and copper alloys, which is five t...
For example, the commonly used square shell battery cells for power batteries include laser welding of cover explosion-proof valves, laser welding of pole columns, and laser welding of cover plates and shells. During the process of laser welding of aluminum alloy, it is easy to generate unqualified phenomena such as explosion points, pores, welding cracks, excessive depth and width of fusion. ...
