Recently, Coherent, an industrial laser technology giant, announced the launch of a new 2D laser cutting head - CUT12, which combines excellent performance, high versatility, and profound value for the global flat cutting market. Image source: CoherentThe CUT12 sheet metal laser cutting processing head is perfectly compatible with fiber lasers in the power range of 4 kW-12 kW (continuous wave),...
Light can calculate functions during propagation and interaction with structured materials, with fast speed and low energy consumption. The use of all optical neural networks for general computing requires an optical activation layer with nonlinear dependence on the input. However, existing optical nonlinear materials either have slow speeds or very weak nonlinearity at the level of natural light ...
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...
Researchers have shown that dissipative Kerr solitons (DKS) can be used to create chip based optical frequency combs with sufficient output power for optical atomic clocks and other practical applications. This progress may lead to chip based instruments being able to perform precise measurements that were previously only possible in a few specialized laboratories.Gr é gory Moille from the ...
