Generation of intense, fully coherent radiation with wide spectral coverage has been a long-standing challenge for laser technologies. Several techniques h
It is well known that seeding can be used to produce narrow-bandwidth and fully coherent x-ray free-electron lasers (FELs). Self-seeding, which uses an ext... Y Ding,Z Huang,RD Ruth - 《Review of Modern Physics》 被引量: 63发表: 2010年 Transform-Limited X-Ray Pulse Generation from ...
Enormous advantages can be brought by using silicon as a substrate for III-V photonic integrated circuit quantum dot (QD) lasers, such as a low cost, high bandwidth transmission data, on-chip light sources, etc. However, several difficulties arise when III-V QD lasers are grown directly on ...
Holographic three-dimensional display is an important display technique because it can provide all depth information of a real or virtual scene without any special eyewear. In recent years, with the development of computer and optoelectronic technology,

Many polarisation techniques have been harnessed for decades in biological and clinical research, each based upon measurement of the vectorial properties of light or the vectorial transformations imposed on light by objects. Various advanced vector measurement/sensing techniques, physical interpretation metho...

This review includes a general introduction (Section 1), the theoretical models of six categories of fractional vortex beams ranging from fully coherent to partially coherent (Section 2), propagation properties (Section 3), classical experimental generation methods of different categories of fractional ...
they store the data as they were gathered in the field, together with all the additional information needed to generate a coherent point cloud with a unified coordinate system. Structured point clouds are frequently generated in ground-based laser scanning (specifically in TLS) and with depth-camer...
In addition to PINN and LSTM, FNN with fully connected network architecture [59,60,61,62] has been successfully used for the end-to-end dynamics prediction of nonlinear optical fiber systems. CNN with cascaded convolution layers and pooling layers has also been introduced to further simplify the...
