Elliptical polarization

Various kinds of lasers are available; they are differentiated by the medium that produces the laser beam. Each of the different types of lasers has a specific range of utility, depending on its wavelength and penetration.

The laser light pulses target red pigment (haemoglobin). Typical settings employed for the treatment of facial veins include a 50 milliseconds pulse duration, and fluence (ie output energy) of 150¬250 J/cm2 (measured in Joules per centimetre squared).

Light pulses target the hair follicle, which causes the hair to fall out and minimises further growth. Typical settings employed include pulse durations of 2 to 20 milliseconds and fluences of 10¬40 J/cm2.

The acronym ‘LASER’ stands for light amplification by stimulated emission of radiation. A laser works by emitting a wavelength of high energy light, which when focused on a certain skin condition creates heat and destroys diseased cells. Wavelength is measured in nanometres (nm).
