Virtual and Physical Prototypes: X-ray laser direct writing 3D nanolithography.Multi-photon polymerization (MPP), also known as 3D nanoprinting, has been investigated using wavelength-tunable femtosecond lasers. At a fixed pulse width of 100 fs, any spectral color in the range of 500nm to 1200nm can be used, which reveals the interaction of more subtle photophysical mechanisms than two-photon phot...
Recently, American laser cleaning system developer Laser Photonics announced that the company has successfully secured an order for a cleaning technology laser cleaning system from Lufthansa Technik Puerto Rico, a technology subsidiary of Lufthansa, the largest aviation group in Europe.Lufthansa Technik is the world's largest independent provider dedicated to providing maintenance, repair, and com...
Professor Zhang Huaijin and Yu Haohai from the Institute of Crystal Materials of Shandong University (the State Key Laboratory of Crystal Materials) proposed a spatial harmonic modulation strategy, which realizes the phase matching conditions that can be manipulated artificially in the new quartz crystal, and realizes the effective frequency doubling within the VUV range. The relevant research is ...
IntroductionThe small hole mode swing laser welding has gained increasing recognition due to its ability to bridge gaps, refine microstructures, and enhance the mechanical properties of welds. However, the effects of amplitude, frequency, welding speed, laser beam power, and beam radius on heat flux distribution, melting mode, and three-dimensional temperature field have not been well understood. ...
Laser Cladding, also known as laser cladding or laser cladding, is a method of adding cladding material to the surface of the substrate and using a high-energy density laser beam to melt it together with the thin layer on the surface of the substrate. It forms a metallurgical bonded additive cladding layer on the surface of the substrate, which can be used for surface strengthening and defect repa...
