Huge energy: Canadian scientists have successfully demonstrated in the laboratory how to guide the flash arc to develop according to a predetermined path, thereby avoiding some objects.
The researchers say that in theory, you can let the arc propagate along an S-shaped path or any other shaped path.
Beijing time on June 23, according to the British "Daily Mail" reported that scientists recently said that in the future humans will be expected to use laser technology to tame lightning and guide them to avoid buildings.
At present, installing lightning rods on top of tall buildings can increase the probability of lightning striking the same location, but the exact path of lightning is still unpredictable. In recent days, Canadian scientists have successfully demonstrated in the laboratory the method of guiding the flash arc to develop according to a predetermined path. They used the Advanced Laser Light Source facility to direct artificial lightning around objects. The study was conducted by the National Research Institute of Canada (INRS) and the results of the study have been published in the journal Science Advances, a journal of Science. This technology will be of potential importance to the industry, and high-voltage arcs from lightning will be of great use in many ways.
Yves Bégin, deputy director of research and academic affairs at INRS, said: “Even without considering our fascination with lightning and arc, this scientific discovery itself will have great potential and open up new research areas. door."
In the current technical field, arcs have been used in engine engines, pollution control technology, lighting, machining and micromachining.
According to Professor Roberto Morandotti, the results of this research will greatly expand the application of this technology. Professor Roberto is the scientist who led the research at INRS. His team used a laser beam to direct a beam of discharge current along a smooth parabolic path. The model shows that laser technology with proper layout will be able to impart some properties to the arc and direct its propagation path. The researchers say that in theory, you can let the arc propagate along an S-shaped path or any other shaped path.
Beacon said: "This important development is achieved on a few centimeters scale, which requires high-energy lasers and can only be achieved with state-of-the-art facilities and state-of-the-art research environments, and INRS can provide us with all These conditions are needed."
Professor Morando Di is currently working with his research team on the so-called "laser self-repair" technology. The technique is simply that when a laser beam is interrupted by an obstacle located on the propagation path, the laser beam can "self-rebuild" once it passes through the obstacle. In this technology study, scientists placed hypothetical obstacles between two electrodes and performed electrical discharge experiments. They observed that the arc could cross the obstacle and pass it without damaging the obstacle and re-form the beam on the other side, indicating that its propagation path is pre-set.
