One type of laser, known as an alexandrite laser, employs an alexandrite crystal as the medium or source of the laser. In the infrared spectrum region, the alexandrite laser emits light with a particular wavelength (755 nm). It is a type of laser known as a red light laser.
The Q-switched mode is another option for Alexandrite lasers, which are also accessible. The process of causing the laser to produce a high-intensity beam in extremely brief pulses is called “Q-switching.”
Alexandrite laser hair removal machine works because the infrared beam emitted by the alexandrite crystal is amplified by repetitive pumping, with each pulse lasting for about 100 femtoseconds.
Because of its strictly controlled wavelength, the alexandrite laser can produce very accurate ablation. It can also be used in dentistry to remove stains on teeth or to assist in gum reshaping.
How does an alexandrite laser work?
The laser emits a wavelength of high-intensity light, which is converted to heat energy, which then causes damage to the area that is being targeted specifically. Therefore, alexandrite lasers function by a process known as photothermolysis, which refers to the utilization of light (photo) to heat (Thermo) in a particular region to cause destruction (lysis).
Alexandrite lasers lead to tissue destruction in a very targeted manner, sparing the healthy tissue in the surrounding area while effectively treating the lesion at hand.
The alexandrite laser can be used in many different ways. For example, it treats areas affected by cuts, wounds, and gums. It can also remove small lesions (such as hair-growth marks), remove stains on teeth, and promote collagen formation in soft tissue such as facial skin and gum tissue.
What is an alexandrite laser used for?
Pigmented lesions: Alexandrite lasers work by destroying the surface of the lesions. For pigmented lesions such as melasma, alexandrite lasers break down pigment through photothermolysis.
Tattoo color: Alexandrite laser removal is also recommended to remove tattoo colors. The same mechanism is used to remove the scar color when treating scars and burns. Alexandrite laser treatment is also used to treat pigmentation marks on faces and hands, stretch marks, skin discolorations, and hyperpigmentation disorders such as melasma (coloration disorder).
Hair removal: Alexandrite laser removes hair on the face, body, leg, and arm. Hair removal is both aesthetic and functional. This is because it helps remove unwanted hair from places it is not essential to keep, such as unwanted moles or growths on the face or body. It also helps achieve a better result in areas with many hair follicles. TheND YAG laser hair removal machine can also treat hair removal!
Vascular lesions: One of the main advantages of using the alexandrite laser is that it can be used to destroy small lesions on the skin, such as angiomas (small spots caused by damaged and dilated blood vessels), cherry hemangiomas (small spots with red marks and some swelling), spider veins, varicose veins, and tiny capillary vessels.
The Bottom Line!
The Alexandrite laser concentrates light on a specific target to cause destruction or damage. It is used in medicine, dentistry, and cosmetology to treat different lesions. It can rapidly remove pigmentation marks, dark spots, tattoos, blood vessels, hyperpigmented skin areas such as melasma spots, vascular lesions, and hair growth.
