What is the diode laser?

The diode laser emits light in the visible infrared range. It is in the semiconductor category. In semi-conductor lasers, reflects of light beams are on the chromophores of the target area in a narrow range. This laser penetrates deeper into the skin, making it one of the best technologies available for excessive hair removal despite the laser wavelength of 800-810 nm.

How does the diode laser work?

Diode laser is one of the semiconductor lasers. (known as diode lasers or injection lasers). Semiconductors are made of two adjacent pieces of p-region (electron acceptor) and n-region (electron donor).

When the two are bound, a region called the p-n junction is available where the laser operation takes place. Free electrons pass through this area from n-region to p-region. The electron gains energy when it enters the junction, and when it enters the p-region, it loses this energy in the form of photons. If p- and n-region are connected to positive and negative poles of an electrical source, respectively the electrons move from n-region to p-region, causing the formation of a large concentration of active substances in the p-n junction.

 

Electromagnetic radiation is a result of losing a photon. Polished junction is a key role for a laser cavity creation. These types of lasers are made in such a way that the laser beam is amplified using the refractive index as well as p and n components. This is one of the weaknesses of semiconductor lasers because as the temperature changes, the refractive index and consequently the properties of the resulting beam change. For this reason, diode lasers are highly sensitive to temperature changes. Diode laser is the most suitable laser for Iranian skin types.

Diode laser applications

The main application of the diode laser is the Removal of excessive hair. The good news is that due to the technology used in the diode laser, this laser can easily be used for full-body hair removal. The most important areas where a diode laser can be used are as follows:

  • Armpit
  • Waist
  • Chest
  • Legs
  • Bikini (men and women)
  • Upper lip
  • Chin
  • Beard

What Should You Do Before Having Treatments?

Before diode laser therapy, clean the area from any cosmetics. Observe personal hygiene and shave the area. The best way is to use a razor. Avoid direct exposure to sunlight, and if you have recently used a solarium, take another time for diode laser therapy.

What Should You Do After Having Treatments?

To reduce redness and inflammation of the skin, avoid exposure to direct sunlight and apply sunscreen. Avoid wearing tight clothing until complete relieve of skin inflammation . Wearing loose and cool clothing prevents skin irritation and helps with treatment that is more effective.

How Many Sessions Do You Need?

Depending on the type of hair (thickness), it is usually between 6-10 sessions at regular intervals. Session time can vary from 30 minutes to 1 hour, depending on the treatment area. Treatment intervals are usually one month, and after a few sessions, you can see the effect of the laser on removing excessive hair. Of course, items such as age, gender, and the treatment area are also important in determining the number of sessions.

What Are The Benefits Of The Diode Laser?

The diode laser has more advantages compared to other hair removal devices. Although some of considerable advantages are as follows:

  • More penetration depth
  • Low risk due to uniform pulse
  • Surface cooling
  • Usable on dark skins
  • Covering a wider area of skin

Complications 

Itching, skin inflammation, and sometimes bleeding are some of the side effects of diode laser therapy. However, do not worry. All these complications, especially bleeding, are short-live and disappear after the treatment session.

Reports show no specific cases or rare side effects with diode laser therapy.

What is the best diode laser device?

If you are seeking the best laser device and you want to permanently get rid of excessive hair, we suggest using the HS-811 diode laser and Selene diode laser devices. By referring to the page of each of these devices, you can gain full access to their capabilities and technologies used in them.
