Properties of Laser Light

Laser light is mono-chromatic, meaning that the light energy is concentrated within a very tight spectral (wavelength) band. Since water, and by extension, tissue interacts with different light wavelengths differently, a specific laser wavelength is chosen to achieve certain clinical results. For example, if tissue ablation is desired, selecting a laser wavelength that is highly absorbed by water creates the required ablation effect.

Laser light is also directional and coherent, which means that it can be targeted accurately and with very high intensity. In a clinical environment, laser light is delivered only where needed thereby minimizing any collateral tissue damage.
