Recently, nLIGHT, a leading company in the fields of fiber optics and semiconductor lasers, announced the launch of two new laser technologies at The Battery Show North America: WELDForm and Automatic Parameter Adjustment (APT), aimed at meeting the dynamic needs of advanced battery manufacturing customers. In order to provide high-quality laser welding technology to the rapidly growing electric...
Femtosecond laser emits ultra short light pulses with a duration of less than 1 picosecond, reaching the femtosecond domain. The characteristics of femtosecond lasers are extremely short pulse width and high peak intensity.Ultra short blasting can minimize waste heat, ensure precise material processing, and minimize incidental damage. Their peak intensities can cause nonlinear optical interactions...
Ultra short laser pulses for local welding (Source: Fraunhofer IOF)With the accelerated evolution of electronic devices towards high power, high frequency, and miniaturization, ceramic substrates have become core materials in fields such as power semiconductors, 5G communications, and new energy vehicles due to their excellent thermal conductivity, insulation, and high temperature resistance. H...
Recently, the research team of the Special Glass and Fiber Research Center of the Advanced Laser and Optoelectronic Functional Materials Department of the Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, aimed at the demand for in-situ detection of Raman signals, expanded the functions of the laboratory commercial Renishaw Invia confocal micro Raman spectrometer by usi...
Recently, scientists used laser gyroscopes to measure that the change in Earth's rotational speed is less than one millionth. This technology can help scientists understand the complex flow of water and air, which can cause the smallest adjustments to the Earth's rotation.The Earth's rotation is not completely stable. Planets accelerate or slow down as they rotate, slightly shortening or prolongin...
