Superlenses are nano artificial structures that can manipulate light, providing a technique that can significantly reduce the size and thickness of traditional optical components. This technology is particularly effective in the near infrared region, and has great prospects in various applications, such as LiDAR, which is called "the eye of autonomous vehicle", mini UAV and blood vessel detector.D...
Sivers Photonics, a leading UK-based supplier of optical fiber communications and III-V semiconductor Photonics devices, has announced that it has received an initial order from UK-based laser developer Vector Photonics to evaluate epitaxial materials for a new next-generation surface-coupled laser project.The order, which includes laser manufacturing and life testing, will be the first time the t...
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 ...
China's laser industry began in the 1980s, when the first private laser enterprise, Chutian Industrial Laser, was founded in 1985 by Sun Wen, an alumnus of Huazhong University of Science and Technology. In the 1990s, some young people with dreams began to make their mark in the laser industry. In 1995, Gao Yunfeng, 29, rented an apartment in Huaqiangbei with a deposit of 400,000 Hong Kong dollar...
Femtosecond laser emits ultra short light pulses with a duration of less than 1 picosecond, reaching the femtosecond domain. The characteristics of femtosecond lasers are extremely short pulse width and high peak intensity.Ultra short blasting can minimize waste heat, ensure precise material processing, and minimize incidental damage. Their peak intensities can cause nonlinear optical interactions...
