The interaction of a high-intensity laser with a fixed target could one day serve as the basis for a tabletop source of high-energy ions for medical applications. An international team of physicists led by the LMU in association with the Munich Center for Advanced Photonics (MAP), a cluster of excellence in Munich, and in collaboration with scientists from the Max Planck Institute for Quantum Optics, are taking another step in this direction One step closer to the goal. They did this by improving the efficiency of a technique that uses an extremely powerful high power laser pointer for ejecting packets of high-energy ions from a diamond-like carbon foil.
Do not use the laser pointer directly at the aircraft
Physicists need powerful laser pointers and find ways to ensure that more incident light is delivered to the carbon foil target in a concentrated form. MAP physicists have now taken an important step towards the latter goal. But she started doing it before she even used a laser pointer. The red dot keeps them from doing more digging because it gives me the (only valid) way to "call" them right away. Only stupid when she digs for him. Each green laser pointer pulse fired at the target lasts 50 femtoseconds (a femtosecond is one millionth of a billionth of a second) and consists of about 20 light field oscillations. This means that not all the electromagnetic energy associated with the light pulse reaches the channel at the same time. It occurs in a dispersed form, so that the radiation pressure acting on the target atoms gradually increases to a maximum value and then decreases. Fort Beeker police spokesman Matthias Auer would like to point out that the use of a laser pointer on a helicopter is a criminal offense due to dangerous interference in air traffic, and Fort Beeker prosecutors have initiated a corresponding action. investigation.
Temporary glare from laser pointers can cause afterimages or so-called "flash blindness". This can be a factor that compromises flight safety, especially during the landing phase of an approach. Absolute glare occurs when the eye cannot adequately adapt to the lower brightness of the rest of the field of view due to interfering light sources. Blinding by a green laser sight can have fatal consequences during the decisive phase of an approach/departure or during low-flying flights that require the absolute attention of the crew. If the pilot temporarily loses control of the plane or helicopter due to blindness, the worst-case scenario could be an aircraft accident.
