What does a femtosecond laser do?

Femtosecond laser is a kind of laser that runs in the form of pulses. Its duration is very short, only a few femtoseconds. One femtosecond is 1-15 seconds, that is, one trillionth of a second. It is several thousand times shorter than the shortest pulse obtained by electronic methods. It can effectively treat myopia and is the shortest pulse that human beings can obtain under experimental conditions at present.

Femtosecond laser has a very high instantaneous power, which can reach tens of billions of watts, which is 1 times more than the total power generated in the world at present. The third feature of femtosecond laser is that it can focus on a space smaller than the diameter of a hair, so that the intensity of electromagnetic field is several times higher than the force of nucleus on electrons around it. Help us treat myopia.

Femtosecond laser, which gives off huge power in an instant, is more than the total power generated in the world, and has been applied at present. Scientists predict that femtosecond laser will play an important role in the generation of new energy in the next century.
