The word LASER is actually an acronym for Light Amplification by Stimulated Emission of Radiation.
Inside a laser device, energy excites a specialised material called the laser medium.
As that energy builds and reflects between two mirrors, it produces something ordinary light cannot: a highly organised beam of light.
Sunlight contains many different wavelengths, with light waves travelling in multiple directions and with no fixed relationship to one another.
LED light can emit a relatively narrow range of wavelengths and often appears as a single colour, but its light waves are not coherent and spread out as they travel.
Laser light is unique because it is:
• Monochromatic – one precise wavelength
• Coherent – all light waves are perfectly in phase
• Collimated – travelling in a tightly focused, nearly parallel beam
These three properties allow laser energy to interact with tissue in a highly controlled way.
The wavelength determines which tissue structures absorb the energy and how deeply it penetrates.
In scar management, this allows specific skin layers and tissue targets to be treated while largely preserving the surrounding tissue.
Not all light is the same. Laser precision is built into the physics—and that's what makes laser treatments so clinically valuable.
