Diode lasers

Diode laser: application, features, and equipment capabilities

Modern lasers are widely used in aesthetic medicine today. It is hard to imagine a beauty salon without a diode laser or other laser equipment. Diode lasers have found their application in the beauty industry. The beam of light generated by a diode laser, with a wavelength of 808 nm, is considered the most effective and painless tool for removing hair on the face and body today. 808 nm is the gold standard in laser hair removal.

The Czech company Alvi Prague closely monitors the trends in high-tech hardware cosmetology. Health and beauty industry professionals are offered effective and safe diode lasers for laser hair removal and other aesthetic and therapeutic procedures.

How a diode laser works

Everyone is familiar with an LED – a semiconductor element that, when a direct current passes through it and an electronic p-n junction occurs, emits light particles—photons. Such radiation is called spontaneous. But under certain conditions, the emitted photon manages to generate its twin brother in the p-n junction area. This leads to something like a chain reaction. This is called stimulated emission or laser generation. The beam generated by the diode laser itself is not stable; a focusing lens is necessary for its concentration.

After passing through a fiber optic light guide and a lens, the generated beam reaches its target—the hair follicle in the patient's skin. The energy of the photons is instantly transformed into heat. It leads to the immediate heating of the sensitive dark pigment in the hair bulb, which consequently dies irreversibly.

The procedure is practically painless, unlike most types of epilation. A special cooling element built into the diode laser handle prevents burning of the skin surrounding the hair bulb. All data are projected onto the control unit's display, and in case of an emergency, the doctor can instantly change the mode of the diode laser or stop the procedure.

Who needs a diode laser?

Diode lasers are recommended for:

• Excessively active hair growth;
• Hair presence in skin folds (e.g., under the breasts in women);
• Irritation (blue beard effect) after unsuccessful traditional waxing;
• Removing ingrown hairs. The device can be used on any part of the body, including the face, underarms, and bikini area.

Contraindications for laser hair removal with a diode laser

Cosmetologists must remember that the diode laser should not be used:

• In type 1 diabetes;
• With malignant neoplasms;
• During exacerbation of simple herpes and other infections caused by Herpesviridae pathogens in the area where the laser hair removal procedure will be conducted;
• With intense tanning and fresh sunburns.

How to choose the right diode laser in the USA and the UK?

In the USA, you can buy dozens of models of diode lasers and other laser devices for painless removal of unwanted hair. When choosing equipment for a spa salon or cosmetic clinic, owners evaluate how quality and safe the procedure is and the attractiveness of the device's design. The ergonomics and functionality of the equipment, ease of operation, and the service offered by the manufacturer also play a significant role.

At Alvi Prague, customer orientation is always top-notch! If you want to buy a diode laser but are not sure which device to choose, our company specialists will consult you in detail and provide equipment for a free test drive.

Currently, our catalog features several laser hair removal devices. They vary in size of the effective light spot (from 1010 mm to 1515 mm) and the total resource of the working handle (from 10 million to 50 million light pulses), as well as the duration of the pulse. All equipment features stylish design and will perfectly fit into the interior of a private cabinet, salon, or clinic. Equipping your workplace with a diode laser and the latest laser equipment, you confirm that you keep up with the times and earn the unconditional trust of clients.

Safety technique

By default, the diode laser is considered a high-risk technique due to the risk of damaging the eye retina with a laser beam. Our company specialists will conduct the necessary training on the diode laser or organize full training for your staff. As a result, the diode laser will bring good mood and aesthetic effect to your clients and elevate your business to a new quality level.
