How to repair laser pointer?
Based on an infrared red laser, it can detect food fraud and ensure the quality and safety of food on our tables. We are currently in the pilot phase, but we intend to develop portable and convenient tools for fast and accurate analysis of food in stores and manufacturing plants that will be available to all institutions involved in monitoring and to all industries and distribution chains that rely on it. while maintaining high quality standards. World powers are even more frequently testing the latest combat developments - red lasers, hypersonic aircraft, drones and weapons samples - with new physics. The CNN television channel previously reported on the testing of laser weapons by U.S. naval forces in the Persian Gulf.

Russia conducts ice-breaking experiment
The Russian holding "Schwabe" and the All-Russian Institute of Civil Defense and Emergencies of the Russian Ministry of Emergencies agreed to test a ship's laser designator for an icebreaker. Today, all icebreakers in Russia traverse ice sheets mechanically: they cut the ice with the help of sharp stems or break it up under their own weight. Recently, scientists realized they could restore the intense stellar pressure by hitting nanowire arrays with ultrashort laser pulses using a much smaller high power laser pointer. The researchers measured the X-rays emitted by the irradiated array, revealing the penetration of extreme energies into the microstructure of the nanowires. Blue lasers should be the replacement for these tools. After the "Schwabe" hut, the laser device can cut ice more than 1 meter thick.
Dave Armstrong, spokesman for MBDA, said: "Dragonfire will leverage joint MoD/industry experience in complex weapons environments to put the UK at the forefront of high-power 30,000mW green laser pointer designator systems. A security expert last week A simple off-the-shelf laser pointer could be combined with a very simple computer to wreak havoc on the thousands of dollars worth of laser pointers or lidar systems installed in most self-driving cars, warn the researchers. Vulnerabilities in driving cars—especially their sensors—seem to be the technology most vulnerable to simple attacks. To actually break into the system, they devised a simple setup that includes a low-power red laser and a pulser.
