Virtual and Physical Prototypes: X-ray laser direct writing 3D nanolithography.Multi-photon polymerization (MPP), also known as 3D nanoprinting, has been investigated using wavelength-tunable femtosecond lasers. At a fixed pulse width of 100 fs, any spectral color in the range of 500nm to 1200nm can be used, which reveals the interaction of more subtle photophysical mechanisms than two-photon phot...
Recently, the reporter learned from Changguang Satellite Technology Co., Ltd. (hereinafter referred to as "Changguang Satellite") that the company used a self-developed vehicle mounted laser communication ground station to conduct satellite ground laser high-speed image transmission experiments with the onboard laser communication terminal of the "Jilin No.1" constellation MF02A04 satellite and ac...
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...
The latest progress in X-ray laser technology has opened up a new era of nanoscale exploration, bringing unprecedented opportunities for materials science and nanotechnology. Researchers have developed a novel imaging technique that can directly visualize separated nanosamples in free flight, capturing their complex structures with stunning details. This breakthrough method relies on single cohere...
TAU Systems, a manufacturer of ultra fast compact laser plasma accelerators, announced today that it has successfully upgraded the existing desktop terawatt laser (UT 3) at the University of Texas to a new and improved performance that provides power for compact particle accelerators. The upgraded UT 3 driver laser can now generate ultra short pulses with a peak power of 40 terawatts.This upgrade ...
