In the interaction between ultra short and ultra strong laser and matter, electrons with short pulse width and high energy are generated, commonly referred to as "hot electrons". The generation and transport of hot electrons is one of the important fundamental issues in high-energy density physics of lasers. Superhot electrons can excite a wide range of ultrafast electromagnetic radiation, as well...
The well-known journal Optica published a paper in November 2024 titled "Near complete extraction of maximum stored energy from large core fibers using coherent pulse stacking amplification of femtosecond pulses"The authors of the paper were the University of Michigan, Lawrence Berkeley National Laboratory, Peking University, and the German Institute of Synchrotron Radiation.The specific technique...
As a promising imaging modality that combines the high spatial resolution of optical imaging and the deep tissue penetration ability of ultrasound imaging, photoacoustic microscopy (PAM) has attracted a lot of attention in the field of biomedical research, and has a wide range of applications in many fields, such as tumor detection, dermatology, and vascular morphology assessment. Depending on the...
The Mitsubishi GX-F Advanced series of artificial intelligence enabled fiber lasers now use patented gas and burr reduction technology to help improve cutting quality while reducing gas consumption when cutting low-carbon steel.Mitsubishi Laser's proprietary Agr Mix nozzle technology does not require an external mixing tank or high-pressure oxygen. The combination of low-pressure air and nitrogen ...
Optical equipment is an integral part of technologies such as data centers and autonomous vehicle, which are constantly developing to meet the needs of complex applications. The challenge faced by designers is to manipulate light at the wavelength scale to achieve the required optical properties, which requires precision at both the nano and macro scales. Nanoscale structures, such as those on LED...
