Opton Laser commercializes ultra-high contrast third-order autocorrelators

With the development of groundbreaking components for terahertz quantum cascade lasers, a huge leap has been made in the field of laser technology. A group of researchers have successfully designed a broadband single-chip external coupler with the potential to redefine the functionality of terahertz QCL.The new external coupler is fundamentally based on planar bimetallic waveguides. Its design is ...

Recently, the research team of the State Key Laboratory of High-Field Laser Physics at the Shanghai Institute of Optics and Fine Mechanics of the Chinese Academy of Sciences has made progress in using high-field lasers to drive the even harmonic frequency shift of single-layer MoS2. The results were published in Optics Express under the title "Frequency shift of even-order high harmonic generation...

Safran Group showcased a 3-foot diameter turbine aft casing manufactured using additive manufacturing technology under the RISE technology program at the Paris Air Show in recent years. This component is Safran's largest additive manufacturing component to date, indicating the increasingly widespread application of additive manufacturing in the design and manufacturing of turbofan engines. In ea...

AbstractDue to the width of the laser melt pool and the sintering effect on the surrounding powder, the experimental size of the selective laser melting (SLM) sample will be larger than the design size, which will greatly affect the dimensional accuracy and surface quality of the thin-walled sample. In order to obtain SLM thin-walled TC11 specimens with precise dimensions, an orthogonal experiment...
