Recently, we did experiments and were surprised to find that the laser can actually cut hair without damaging the hair follicle tissue. Using a ruby pulsed laser, the pulse width is adjusted at 0Between 5-3ms, the hair on the surface can be removed without damaging the hair follicle tissue. Strict control of the laser energy density can achieve a perfect bald hairstyle, which is currently only used for this kind of hairstyle, and nothing else will be found.
When it comes to lasers, most people may think of lasers used for laser marking, laser cutting, and laser welding, which are easy to access in life, but these lasers cannot be used to remove hair, let alone haircuts, lasers are characterized by different wavelengths of lasers that react to different substances, especially conductors, semiconductors, and insulator materials. For example, lasers used to process metallic materials have little reaction to insulator materials. The hair on the surface of the animal ** belongs to the insulator, and the carbon dioxide laser has a very high absorption rate of the insulator material, if the carbon dioxide laser is used to remove the hair of the pig's head, it is easy to damage the substrate at the same time, so it is not suitable.
Dun Lei is specialized in laser cleaning, not laser haircuts, the process of haircutting is discovered by chance, there is no practical value for us, maybe it will have a reference role for other peers, so the experimental process is shared for reference, if there is a barber shop wants this technology, we transfer it for free.
The ruby laser wavelength is 6943nm, we use a pulsed laser, this wavelength of laser belongs to visible light, we use it to remove the pig's head, and found that as long as the appropriate pulse width is adjusted, the pig's hair can be perfectly removed without damaging the pig's head. After repeated tests, there really was no damage to **, and we tried an idea, what would happen if we gave people a haircut?We first found some hair from the barber shop and tested it with a laser, and found that the hair was similar to pig hair, with a wavelength of 694The 3nm laser has an extremely high absorption rate, and at the same time, it also has a high absorption rate for **. Therefore, as long as you adjust the parameters and find the parameters that just remove the hair without damaging it, you can get a perfect haircut. We adjusted the pulse width with the determination of the power and found that the pulse width was at 0Between 5-3ms it just removes hair without damaging it**.
