In the long run, electrons accelerated by highly repetitive PW-level pulses can drastically reduce the cost of the machine that particle physicists dream of building. Their dream was to build a 30-kilometre electron-positive laser pointer collider that could replace the Large Hadron Collider at the European Nuclear Research Council near Geneva, Switzerland.
Plasma physicists at Imperial College London in the UK said that compared with machines currently costing about $ 10 billion, 100PW laser-based equipment would be at least 10 times shorter and costs would be reduced by at least 1/10. In the field of measurement, laser ranging is a good way to save time and labor when we are in danger of climbing when measuring altitude and when we are troubled by the measurement curve.
The principle of laser ranging is that after laser pointers are aimed at a target and emitted, the round-trip distance is measured by measuring its round-trip time and then multiplied by the speed of light. In the 1980s, Leica developed the world’s first handheld laser rangefinder, which was as large as a brick and very heavy. At this time, China’s laser industry has just begun.
