What is the Medlite q-switched laser?
There are a number of medical lasers, each designed to target different problems. This page will discuss the Medlite q-switched laser, which has two frequencies for the treatment of skin conditions, namely, 532 nanometres (KTP), and 1064 nanometres (Nd:YAG). The main feature of this laser is that it has extremely short pulses of high power that can be shorter than 20 nanoseconds (one nanosecond equals one billionth of a second). This allows this laser to have a photo-mechanical effect on skin pigmentation and tattoo inks or pigments, literally shattering these small particles. The remnants are then removed by the body’s immune system. The laser light emitted also operates by the principle of selective photothermolysis, which is the attraction of particular wavelengths of the laser to be attracted to certain colours, allowing for the specific heating and targeting of a coloured target. For example, the 532nm wavelength is highly attracted to red tattoo inks. Therefore, by using the 532n
