Terahertz waves have significant application value in communication and imaging. The nonlinear interaction between strong field ultrafast laser and matter is one of the important ways to generate terahertz waves. The experimental and theoretical research related to terahertz generation media such as plasma, gas, and crystal is relatively sufficient. However, liquid water is a strong absorbing medi...
The attosecond level ultra short laser pulse provides a powerful method for detecting and imaging ultra short processes, such as the motion of electrons in atoms and molecules.Although ultra short laser pulses can be generated, generating ultra short and high-energy pulses is a continuous challenge. In order to expand the photon energy, photon flux, and continuous bandwidth of isolated attosecond ...
High-tech and industrial laser company Trumpf has reported rather negative preliminary trading figures for the fiscal year (FY) 2024-2025, with CEO Nicola Leibinger-Kammüller stating that “the lowest point has been reached.”The Ditzingen, Germany-based company stated that it had ended the latest fiscal year “as expected – with a decline in sales and order intake.” According to preliminary calcul...
The First Ultra Fast Laser Application Development Conference was held in Songshan Lake, Dongguan. The first advanced attosecond laser facility in China will have 8 beam lines landing in Dongguan.Laser enjoys the reputation of being the "fastest knife," "most accurate ruler," and "brightest light," among others. As an important research direction in the laser field, ultrafast laser has always been...
In the era of the Internet of Things, visual image sensors, as key devices in the intelligent society, are embedded in various devices such as mobile communication terminals, smart wearable devices, automobiles, and industrial machines. With the continuous expansion of applications, higher requirements have been put forward for the system power consumption, response speed, safety performance, and ...
