What is a laser? Why can laser cut and sculpt objects? How does human use the laser? Hu Yun will answer your questions one by one

1.Various lights

认识激光

★ The sun transmits energy in the form of electromagnetic waves.

★ Solar electromagnetic waves can be divided into visible light and invisible light according to different wavelengths.

★ The visible light wavelength range is between 0.4 and 0.75 microns, which is divided into seven colors of red, orange, yellow, green, and indigo, which is the color of the colorful rainbow.

★ Lights other than the visible wavelength range are collectively referred to as invisible light, of which the CO2 laser wavelength is 10.6 microns, which is invisible light.

(Small knowledge: the red light beams we see in infrared, ultraviolet, laser and other equipment in daily life are actually visible lights that are added only for easy observation)

2. What is a laser?

认识激光

★ Laser is a collection of high energy beams.

★ Four characteristics of laser: high density: energy concentration; same direction: same direction; same frequency: same wavelength; synchronization: same phase.

★ Ordinary light sources, such as light bulbs, have different photons, and they run around in different directions, which is very ununited, but the photons in the laser are thinking in one place,

They are so powerful and powerful that they can be used to cut and sculpt a variety of materials.

3. How to use laser?

★ The laser can be turned into an automation tool through reflection.

★ Two magic mirrors:

Mirror: change the direction of light.

Focusing lens: reduce the light beam and increase the light density.
