Recently, BLM Group in the United States has launched a new LT12 laser tube system, which performs well in cutting light and heavy pipes and profiles, and can handle materials with a diameter of up to 305 millimeters.According to the company, compared to other similar machines, the LT12 laser tube system reduces cutting time by up to 55% when cutting materials with the same maximum diameter, signi...
Limiting Auger recombination enables “record” quasi-continuous wave laser output.For years, engineers have sought better ways to build tiny, efficient lasers that can be integrated directly onto silicon chips, a key step toward faster, more capable optical communications and computing.Today’s commercial lasers are mostly made from III-V semiconductors grown on specialized substrates—a process that...
Researchers at the University of Bristol have made significant breakthroughs in expanding quantum technology by integrating the world's smallest quantum photodetector onto silicon chips. The paper "A Bi CMOS Electron Photon Integrated Circuit Quantum Photodetector" was published in Science Advances.In the 1960s, scientists and engineers were able to miniaturize transistors onto inexpensive microch...
Lithography machine is the key equipment for making high precision mask plate. Using a very fine laser beam, the highly precise line pattern is drawn on the mask substrate under the control of an extremely precise automatic control system.Laser direct writing is to use a laser beam with variable intensity to implement variable dose exposure on the resist material (photoresist) on the subst...
The beam emitted by almost all laser systems follows the Angle pattern of Gaussian distribution. The Gaussian irradiance distribution means that irradiance has a smooth peak at the center point and slowly declines toward the edge. In theory, the irradiance level of a Gaussian distribution can never reach zero, which means that the distribution can expand indefinitely. This phenomenon in the laser ...
