What is laser crystal?
Laser crystals are quiet unique in their composition and are often doped with various ion types. These ions assist the process of stimulated emission within the crystal to amplify light at a cohesive wavelength. When compared with other laser mediums such as doped glasses, crystals typically have a smaller absorption and emission bandwidth, higher thermal conductivity, and higher transition cross sections. A laser’s transition cross section predicts the likelihood of an induced transition due to radiation. A high transition cross section then correlates to a higher probability of absorption or stimulated emission. Laser crystals can also come in many different shapes. Common geometries of these crystals includes cuboid, cylindrical, and thin-disk. The shape of the crystal along with the doping density greatly influence the output laser beam.

Lasers Selectively Target the Skin
There are different types of lasers based on the kind of light that they emit. The physics behind this is due to different naturally occurring crystals in nature. A crystal can be put into an activated state, and then release light as the crystal relaxes from the activated state.
Lighter vs Darker Skin
It is very important to take skin pigment level into account when designing the right laser treatment. Darker skin will absorb pigment differently and have a greater risk for skin darkening (known as hyperpigmentation), skin lightening (known as hypopigmentation), blistering, and scarring.
Are Lasers the Same as Intense Pulsed Light?
No. They are not the same thing. Intense pulsed light sends a broad pulse of light that is filtered before it is delivered to the skin. Lasers are different in that a crystal is activated to deliver a very narrow band of light energy to the skin.
