At what wavelength is an Alexandrite laser present within the visible light spectrum?

The Alexandrite laser operates at a wavelength of approximately 755 nm, which is situated in the near-infrared part of the electromagnetic spectrum. Although it's close to the visible light spectrum, it is important to note that 755 nm falls just outside the visible range, which typically extends from about 400 nm (violet) to 700 nm (red).

This wavelength is particularly significant in aesthetic dermatology and hair removal because it can effectively target hair follicles while minimizing damage to surrounding tissues. The absorption characteristics of the Alexandrite laser make it a versatile choice, especially for individuals with light to medium skin tones.

Understanding the specific wavelength of the Alexandrite laser helps practitioners choose the appropriate device and settings for desired outcomes while also considering patient safety and comfort.
