Tumor cells that spread cancer via the bloodstream face a new foe: a laser beam , shined from outside the skin, that finds and kills these metastatic little demons on the spot. In a  study  published today in  Science Translational Medicine , researchers revealed that their system accurately detected these cells in 27 out of 28 people with cancer, with a sensitivity that is about 1,000 times better than current technology. That’s an achievement in itself, but the research team was also able to kill a high percentage of the cancer-spreading cells, in real time, as they raced through the veins of the participants.  If developed further, the tool could give doctors a harmless, noninvasive, and thorough way to hunt and destroy such cells before those cells can form new tumors in the body. “This technology has the potential to significantly inhibit metastasis progression,” says Vladimir Zharov, director of the  nanomedicine center  at the University of Arkansas for Medical Scienc

In order to deal with "potential threats" such as China and Russia, the United States continues to raise its chips to "sci-fi weapons." The US Air Force Research Laboratory claims that the latest "Self-Defensive High-Energy Laser Demonstrator Advanced Technology Demonstration Program" (SHiELD) successfully shot down multiple incoming missiles during the test. The US Navy has greater ambitions and plans to install laser weapons for the Aegis destroyers to defend against the "China missile frenzy." However, experts say that even if these plans go well, the US tactical laser weapon system will take at least a decade to put into practical use, and it needs to solve a series of problems such as volume, weight, power supply and range. Started testing on fighter aircraft in 2021 The US military's "Stars and Stripes" reported on the 6th that in a series of tests conducted at the White Sands Missile Range in New Mexico, the "lase

Since the emergence of lasers in rubies in the 19 6 0s, in the same year, calcium fluoride (CaF2:Sm2+) was found to output pulsed lasers. In the second year, pulsed lasers were obtained in ytterbium-doped silicate glass. The rare earth has formed an indissoluble bond. Rare earths have many properties such as magnetism, light, electricity, superconductivity and catalysis. They are one of the most important materials in this century. They are widely used in many fields. As a non-renewable resource like oil, they are valued by many countries. Strategic resources. Since the rare earth was bonded to the laser, the utilization of rare earth in the laser has been deepened. In 1962, the CaWO4:Nd3+ crystal was used to output the continuous laser. In 1963, the rare earth chelate liquid laser material was firstly developed, and the erbium-doped benzoylacetone was used. The pulsed laser was obtained from the alcohol solution. In 1964, the ytterbium-doped yttrium aluminum garnet crystal (Y3Al5

Solid-state lasers with all powers are very diverse. Asia has the fewest products, but it is growing rapidly. Among them, China is playing an increasingly important role. The future of industrial laser applications is limitless. Analysis of global industrial laser applications shows that laser cutting and laser marking are at the forefront. Followed by welding, micromachining and engraving. There are not many applications for laser drilling. Nevertheless, the development of the paper product processing market is promoting the promotion of laser drilling applications. In terms of the installation volume of industrial laser application systems, the increase in installations in China directly expands the share of installations in the Asian laser industry application system, which makes the installations in North America, Europe and Asia relatively flat, around 30%. . The continuous application of laser technology in the industrial field has promoted the development and even leap of the g

Chip-level lasers are born! Ability to emit light with a basic linewidth of less than 1Hz! Spectral pure lasers are at the heart of advanced  scientific and commercial applications due to their ability to produce near-perfect monochromatic light. This ability of the laser is measured based on its linewidth or coherence, that is, the ability to emit a constant frequency over a period of time before the frequency changes. In practice, researchers are doing their utmost to make highly coherent, near-unipolar lasers for  advanced systems  such as atomic clocks. However, today these lasers are bulky and occupy the rack of equipment, they can only be used in the laboratory workbench. There is currently a trend to transfer the performance of advanced  lasers to photonic microchips, which can be applied to a wide range of applications such as spectroscopy, navigation, quantum computing, and optical communications while significantly reducing cost and size. Achieving such performance on a

Fiber laser  advantages : (1) The advantages of miniaturization and intensification brought about by the low manufacturing cost of glass optical fiber, mature technology and the availability of optical fiber; (2) The glass fiber does not require strict phase matching of the incident pump light like a crystal, which is due to the non-uniform broadening caused by the splitting of the glass matrix Stark, resulting in a wide absorption band; (3) The glass material has a very low volume-to-area ratio, and the heat dissipation is fast and the loss is low, so the up-conversion efficiency is high and the laser threshold is low; (4) The output laser has many wavelengths: this is because the rare earth ion energy level is very rich and there are many kinds of rare earth ions; (5) Tunability: Since the rare earth ion energy level is wide and the fluorescence spectrum of the glass fiber is wide. (6) Since there is no optical lens in the cavity of the fiber laser, it has the ad
