2022-12-1447510Laser cutting of metal materialsAlmost all metal materials have high reflectivity to infrared ray at room temperature. For example, the CO2 laser absorption of 10.6 pum is only 0.5%~10%. However, when the focused beam with the power density exceeding 106W/cm2 shines on the metal surface, the surface will start to melt in a few microseconds. The ab...
2022-12-1545800Recently, the State Key Laboratory of Intense Field Laser Physics of Shanghai Institute of Optics and Precision Machinery, Chinese Academy of Sciences has made progress in the field of circularly polarized laser controlling single-layer graphene to generate reverse photocurrent. The relevant research results were published in Optics Express under t...
2022-12-1530400Recently, Yole, a well-known semiconductor analyst, released a report on the laser industry. It is estimated that the edge emitting laser (EEL) market will grow from $3.5 billion in 2021 to $7.4 billion in 2027, with a compound annual growth rate (CAGR 2021-2027) of 13%. Growth will continue to be driven by optical communications, such as optical m...
2022-12-1442000Recently, Xuchuang Technology Research Institute launched the latest research results - the industry's first high-power, antireflection laser. This laser breaks through the dependence of traditional lasers on isolators, and can realize the more advantageous transmission performance in small size pluggable external light source module (ELSFP) and ph...
2022-12-1434600Three photon (3P) excitation of fluorescent proteins and probes has aroused great interest, especially in the field of neuroscience applications. As confirmed by Chris Xu and other researchers, an important reason is that the 1300 nm and 1700 nm wavelength windows used for three photon excitation bring deeper penetration.Three photon excita...
2022-12-1443700Laser cutting operates in continuous or repetitive pulse mode. In the cutting process, the laser beam is focused into a very small spot (the minimum diameter can be less than 0.1mm), which makes the focusing reach a very high power density (can exceed 106W/cm2). At this time, the heat input by the beam (converted from light energy) far exceeds the ...
2022-12-1442700Laser is helping us to develop clean, intensive and efficient fuels, which in turn requires large-scale clean energy production to help solve the world energy crisis. The net energy obtained from fusion reaction may be an important step towards the goal of creating unlimited clean energy in the near future.On December 12, researchers from t...
