Diode Laser Hair Removal

Diode laser uses a combination of layers of different bandgap materials to achieve laser action. These layers are called heterostructures.

The device converts electric energy to light through recombination of electrons and holes in the gain region. These electrons and holes are emitted as photons. This process occurs at a temperature that is dependent on the diode’s operating temperature range.


Diode laser therapy is an effective treatment option for unwanted hair growth, as it destroys the structure of the unwanted hair follicle without harming the surrounding skin. This makes it a safe and effective method for treating the face, underarms, legs, and bikini line. Unlike other methods of hair removal, such as waxing and shaving, the results of laser therapy are long-lasting.

Another advantage of the diode laser is its ability to treat darker skin tones, as it emits a longer wavelength than other types of hair removal lasers. Additionally, the precision of the diode laser allows it to target a specific area without affecting nearby areas. This reduces the risk of causing post-procedural hyperpigmentation, which is common in other hair removal treatments for darker skin tones.

It is important to note that while the diode laser can offer permanent hair reduction, it will require a series of sessions in order to achieve this result. During each session, the number of hair follicles that are targeted will diminish, until you reach the point where there is no more hair growth.

Another benefit of the diode laser is its ability treat conditions such as fibroadenomas, scrotal cysts, hidrocystoma, and mucoid pseudocysts. It has also been shown to be effective in reducing the redness of keloids.

Treatment Options

Laser therapy is an extremely versatile treatment option with diode laser devices capable of producing various wavelengths and power levels. The ability to choose the exact wavelength required for a particular clinical application ensures optimal results with minimum discomfort for the patient.

For example, the 980-nm wavelength of the diode laser is ideal for treating vascular dc to ac converter lesions in the oral cavity because hemoglobin absorbs light at this specific wavelength. In addition, the device can be used to reduce pigmented spots and sun damage with optional wavelengths of 415nm, 560nm, and 640nm in one laser device.

A diode laser can also be used to treat periodontal disease with adjunctive use to scale and root planing (SRP) and improve the prognosis of the gum tissue. Research IC Batteries component has shown that the adjunctive use of a laser device during SRP significantly decreases pocket depth and plaque index (PI) in patients with chronic periodontitis.

The laser device also eliminates the need to use a curette in certain cases, which could lead to bacteremia and other complications. In fact, a study has demonstrated that preprocedural subgingival laser application significantly reduces the incidence of bacteremia in high-risk patients during ultrasound scaling and polishing.


Diode lasers are by far the most popular type of laser used in the dental profession today. They offer a lower cost of ownership, a wide range of output wavelength (color) and power, compact rugged packaging and superior semiconductor technology reliability compared to other laser types.

There is an inherent risk with all lasers. It is therefore imperative that any and all lasers be operated within the safety parameters as set forth by manufacturers, standards bodies, government regulations and the ANSI Z 136.1 Standard. This Standard defines a Maximum Permissible Exposure (MPE) for a specific laser and wavelength. The MPE is the highest level of energy that a laser can deliver for a specified duration without creating any damage to tissues, including the corneas of eyes.

The MPE is based on the principles of the Cosine Law of reflection and Lambert’s Law of light dispersal. In general, a beam’s MPE decreases with the increase in laser beam size and with the change in wavelength of the laser.

Any and all laser systems should be equipped with a defeatable control that is designed to allow rapid egress by all personnel in the laser controlled area and admittance of any person in an emergency condition. This should be a readily accessible “panic button” or control/disconnect switch. Other safety features include key-controlled operation, warning lights to indicate laser light emission, beam stop or attenuator, and electrical contact that can be connected to a fire alarm or interlock.


Laser hair removal with diode technology is an affordable treatment, compared to other options. It can also be faster, and requires fewer sessions than other treatments. Diode laser therapy is also effective for reducing the appearance of fine lines and wrinkles, making it a good option for people with delicate skin.

The cost of a laser diode depends on a few key parameters. The wavelength, power, spectral quality and package type can all affect the price. For example, the price of a diode laser may be much less than a dollar for wavelengths that are used in high volume applications such as consumer electronics or telecommunications.

A diode laser is an effective tool for glaucoma treatment. It lowers eye pressure by causing the fluid-producing cells in the eyes to turn off. This prevents the buildup of fluid, and the pressure is relieved. A diode laser is also used to control pain in glaucoma patients who are too frail for surgery.

The diode laser is a safe, effective treatment for many conditions and diseases. It can be used to treat chronic periodontitis, a painful infection that affects the gum tissue and surrounding teeth. It is also effective for reducing inflammation, bleeding and bone loss. The laser can also be used to help reduce the frequency of periodontal surgery.
