A sketch of the imaging and holographic parts of a transient holographic microscope, including a pulse sequence, to illustrate the signal modulation method. By imaging the pinhole array at the sample position, a diffraction limited excitation spot array can be created, allowing for the simultaneous collection of transient data around 100 excitation spots.Femtosecond transient microscopy is an impo...
The ZEUS laser at the University of Michigan recently achieved a breakthrough of doubling the peak power of the strongest laser in the United States through its first 2 quadrillion watt experiment. Although this instantaneous power only lasts for 25 attosecond (one billionth of a second), it exceeds the total power of the global power grid by more than a hundred times.Karl Krushelnick, director of...
Recently, Professor Ni Zhenhua from the School of Electronic Science and Engineering at Southeast University, Professor Lv Junpeng from the School of Physics, Professor Liu Hongwei from the School of Physical Science and Technology at Nanjing Normal University, and Professor Zhou Peng from the School of Microelectronics at Fudan University collaborated to propose a van der Waals light-emitting dio...
Water helps to generate ultra continuous white lasers with an extremely wide wavelength range.Researchers have made significant progress in creating ultra wideband white laser sources, which have a wide wavelength range from ultraviolet to far-infrared. These advanced lasers are used in various fields, including imaging, femtosecond chemistry, telecommunications, laser spectroscopy, sensing, and u...
Laser cutting is a type of metal processing. In industry, there are three main cutting methods: mechanical cutting, thermal cutting, and a set of high-precision cutting methods. Laser technology belongs to the third category. The cutting in this method occurs due to the influence of the laser beam on the product. In fact, it is the molten metal produced by rapid pulse point melting and then blowin...
