A German 3D printing company applies for bankruptcy

Due to advances in materials science by Stockholm researchers, changing the shape during flight to better handle airflow passing through its aircraft wings may be imminent. The trick involves the melting and drilling capabilities of lasers.Researchers from KTH Royal Institute of Technology in Stockholm, Sweden conducted experiments on paraffin. Using the 2D version of the material, they were able ...

Shenzhen Lianming Power Supply Co., Ltd. (hereinafter referred to as "Lianming Power") announced the completion of a B-round financing of tens of millions of yuan in the near future. The fund managed by Jiangsu Jiuyu Investment Management Co., Ltd. completed the A-round investment in Lianming Power in December 2021. Recently, Jiuyu Investment, as an old shareholder, continued to increase its inves...

Optical metamaterials are an effective way to utilize their superior photon capture capabilities. Therefore, perfect absorbers can be achieved through nanoscale resonant plasmas and metamaterial structures.Metamaterial perfect absorbers (MPAs) are typically composed of periodic subwavelength metals (such as plasma superabsorbers) or dielectric resonance units. Compared with static passive physical...

In a study published in Optics Express, the research team led by Professor Fu Yuxi of the Xi'an Institute of Optics and Precision Mechanics (XIOPM) of the Chinese Academy of Sciences developed the room temperature holmium doped lithium yttrium fluoride (Ho: YLF) composite thin slice laser for the first time, which can achieve high efficiency and high-quality CW laser output.Laser devices operating...

The beam emitted by almost all laser systems follows the Angle pattern of Gaussian distribution. The Gaussian irradiance distribution means that irradiance has a smooth peak at the center point and slowly declines toward the edge. In theory, the irradiance level of a Gaussian distribution can never reach zero, which means that the distribution can expand indefinitely. This phenomenon in the laser ...
