The word LASER is an acronym for Light Amplification
by the Stimulated Emission of Radiation. A laser produces
a beam of highly concentrated light. Different types
of lasers produce different colours of light. The colour
of light produced by a particular laser is one of the
keys to it's effect on hair follicles.
How it works:
Light is made up
of packets of energy called photons. A laser produces
light just like a light bulb; however, there are three
differences between the light produced by a laser and
1) The light from a lightbulb radiates in all directions,and
the intensity of the light decreases as you move away
from the lightbulb. With a laser the photons are parallel,
go in the same direction, and are in phase with each
other, and the intensity does not decrease very much
2) Lightbulbs produce light that
is white or yellow-white because it contains all the
colors and wavelengths of visible light. Laser produces
light of one wavelength and one color.
3) The light from a laser is
much more intense meaning that there are many more photons
per unit area. In fact, lasers produce more photons
than the sun per unit area.
The light emitted by the
LaserLight Diode Laser Is well absorbed by the pigment
located in hair follicles. The laser pulses for a fraction
of a second, just long enough to vaporize the pigment,
disabling numerous follicles at a time to eliminate
or significantly impede hair growth.
