The Advantage Of Femtosecond Laser As An OCT Source

Introduction: OCT combines semiconductor laser, ultra-fast optical technology, ultra-sensitive detection, electronics, computer control and image processing technology in the same system. Compared with traditional detection methods, OCT has high resolution, no harm to samples, and can obtain real-time measurement results of the sample.　　Optical Coherence Tomography (OCT) is a new imaging technique based on low coherence measurement. It can perform non-contact and non-invasive tomography of living tissue microscope structures. OCT is an optical analog of ultrasound with higher longitudinal resolution and does not adversely affect organisms like X-rays and RF electromagnetic fields.Therefore, OCT is particularly suitable for samples with high scattering and non-transparent properties, and organisms are such samples.At present, more and more OCT is applied to the diagnosis of biological tissues, especially the diagnosis of ophthalmology and subcutaneous tissue. Its penetration depth is al...

Nano Laser Probe Research Has Made Important Progress

Recently, the team of Academician Chen Hongyuan from the School of Chemistry and Chemical Engineering in Nanjing University has made important progress in the luminescent probe based on plasma laser system.The rapid development of modern life sciences and medicine relies to a large extent on the advancement and development of luminescent probes. Over the past few decades, humans have created a range of luminescent materials that have been widely used in basic research, medical diagnostics, and the chemical industry. These luminescent probes include: organic fluorescent dyes, semiconductor quantum dots, fluorescent proteins, up-converting fluorescent materials, bioluminescent molecules and so on.Using different color luminescent probes, it is possible to observe the coordinated behavior of multiple biomolecules in a biological system, or to simultaneously analyze disease markers of various characteristics. The luminescent behavior of the above luminescent probes is based on spontaneous ...

Scientists' Next Generation Laser Technology Creates Lightspeed Broadband Connections

According to James Consulting, the European Union team of scientists is using the next generation of laser technology to create a light-speed broadband connection that eliminates Internet data bottlenecks caused by increased demand.The research team is funded by the European Union, consists of researchers from nine countries (Italy, Spain, the Netherlands, Finland, Germany, Israel, France, Japan and South Korea) and 14 different organizations. The team calls itself 'PASSION', meaning: applied to future large-capacity metropolitan area networks, based on scalable spectrum/spatial aggregation of programmable transmission and switching module systems for photonics (creatively selecting letters in English words, the combination is abbreviated as PASSION).The team's researchers are using vertical cavity surface emitting lasers (VCSEL), light sources and photonic integrated circuits, optical switches and semiconductor optical amplifiers to develop long-wave, high-capacity communi...

Roll-to-roll Process Based On Laser-induced Superplasticity

Researchers at Purdue University have developed a new technology—a roll-to-roll laser-induced superplasticity process that can be used to print ultra-fast nanoscale electronic devices.This process is similar to the roll-to-roll printing process of newspaper printing, which can produce smoother, softer metal lines for the production of high-speed electronic devices, greatly increasing the production speed of electronic devices.Mobile phones, laptops, tablets, and many other electronic devices rely on their internal metal circuitry for high-speed processing of information. Current metal circuit fabrication methods generally involve forming a metal line by passing a thin liquid metal droplet through a reticle having a target line shape, which is somewhat like graffiti on a wall. However, the metal lines produced by this technology have a very rough surface, which causes the electronic device to heat up more quickly, thereby draining the battery faster.Future high-speed electronic devices ...
