国内自主研发首套碳化硅晶锭激光剥离设备投产

Scientists at the Technical University of Munich have made significant progress in measuring the Earth's rotation with unprecedented accuracy. Now, the ring laser from the Wettzell Geodetic Observatory can be used to capture data at a quality level unmatched anywhere in the world. These measurements are crucial for determining the position of the Earth in space, assisting climate research, and imp...

The 3500W free output blue semiconductor laser beam is output in a free space manner, with a rectangular spot directly acting on the material surface without the need for fiber optics or laser processing heads. This laser has a wavelength of 455 ± 10nm, with continuously adjustable power and a maximum output power of over 3500W. It is mainly used for non-ferrous metal cladding, quenching, etc., to...

The transmission of electromagnetic waves (such as lasers) in plasma is a fundamental issue in plasma physics. In general, electromagnetic waves cannot be transmitted in high-density plasma, but their transmission and energy transfer play a crucial role in applications such as fast ignition laser fusion, laser particle acceleration, and ultra short and ultra bright radiation sources.In 1996, S. fr...
