What is the wavelength of the Alexandrite laser?

The Alexandrite laser operates at a wavelength of 755 nanometers. This specific wavelength places it in the near-infrared spectrum, which is particularly effective for various aesthetic and medical applications, such as hair removal and treatment of pigmented lesions. The effectiveness of the Alexandrite laser is often attributed to its ability to effectively target the melanin in hair follicles, making it a popular choice for laser hair removal, especially on lighter skin types.

The other wavelengths mentioned in the choices correspond to other types of lasers, each with distinct applications and properties. For instance, the wavelength of 694 nm is characteristic of the Ruby laser, which is more suitable for specific treatments. The 810 nm and 1064 nm wavelengths are associated with Diode and Nd:YAG lasers, respectively, which also have different applications and efficacy based on their distinct wavelengths. Understanding the unique properties of each laser and their corresponding wavelengths is crucial for selecting the right laser for a given procedure.
