Devices For Laser Hair Removal

These are alexandrite lasers, diode lasers, ruby lasers, and NeoDymium Yttrium Aluminum Garnets, that's typically called Nd:YAGs.

Alexandrite lasers became readily available for use in laser hair removal in 1997 when they have been cleared through the FDA. Alexandrite lasers develop light beams inside red spectrum of visible light.

Their wavelength is 755 nanometers which is quite powerful but only safe on light skin. Five diverse forms of the alexandrite laser are available. These involve the Apogee, GentleLase, Epicare, Epitouch Alex, and Ultrawave II-III.

This type of laser has proved successful within the treatment of ingrown eyelashes and works incredibly well on dark hair. The Light SheerXC is usually a diode laser that's very powerful. Other diode lasers consist of EpiStar, Apex-800, Iridex, and Mediostar.

Clinical research showed that the laser damage did not extend far enough down into the hair shafts to result in permanent laser hair removal. Originally there were five varieties of ruby lasers, of which only two are still readily available for commercial use. A Ruby lasers operate on a shorter wavelength system of only 694 nanometers.

The Q, switched NeoDymium Yttrium Aluminum Garnets has a extremely short pulse of about one nanosecond. It is typically measured in milliseconds. Most lasers utilized for hair removal have a maximum pulse duration inside 20 to 40 millisecond range. Each kind of laser produces a specific spot size which is measured in millimeters. Most lasers have three main parts, an power source, and active medium, and an optical cavity, also known as a resonator. The power source is a device that supplies vitality to the active medium. Laser hair removal devices use electricity as their energy source. Lasers are defined by the elements they use.
