Recently, according to a paper published in Nature Communications titled "Phonoenhanced nonlinearities in hexagonal boron nitride," engineers from Columbia University collaborated with theoretical experts from the Max Planck Institute of Material Structure and Dynamics to discover that pairing lasers with lattice vibrations can improve the nonlinear optical properties of layered two-dimensional ma...
A mode-locked laser is an advanced laser that can generate very short optical pulses with durations ranging from femtoseconds to picoseconds. These lasers are widely used for studying ultrafast and nonlinear optical phenomena, but they have also been proven to be applicable to various technological applications.Researchers at the California Institute of Technology have recently been exploring the ...
Laser cladding, also known as laser metal deposition, is a process of depositing one material onto another.When the laser beam scans the target surface, metal powder or wire flow is fed into the molten pool formed by the laser beam, thereby producing the required material coating.The laser cladding method improves the surface properties of the parts, such as wear resistance, and allows for the rep...
The new discovery by optical scientists has brought new vitality to fiber lasers. This innovative method significantly improves the power of lasers without reducing beam quality, and will become an important defense technology for future low-cost drones and remote sensing.The research teams from the University of South Australia, the University of Adelaide, and Yale University have demonstrated ne...
In the era of the Internet of Things, visual image sensors, as key devices in the intelligent society, are embedded in various devices such as mobile communication terminals, smart wearable devices, automobiles, and industrial machines. With the continuous expansion of applications, higher requirements have been put forward for the system power consumption, response speed, safety performance, and ...
