A laser is a device that emits light (electromagnetic radiation) through a process called stimulated emission. The term laser is an acronym for light amplification by stimulated emission of radiation.
Laser light is usually spatially coherent, which means that the light either is emitted in a narrow, low-divergence beam, or can be converted into one with the help of optical components such as lenses. Typically, lasers are thought of as emitting light with a narrow wavelength spectrum ("monochromatic" light). This is not true of all lasers, however: some emit light with a broad spectrum, while others emit light at multiple distinct wavelengths simultaneously. The coherence of typical laser emission is distinctive. Most other light sources emit incoherent light, which has a phase that varies randomly with time and position.
With over 15 years experience using numerous lasers in clinical practice, including their use in the removal of broken blood vessels of the face, hair removal in both fair and dark skin and the use of lasers to remove benign lumps and bumps on the skin including warts and excessive skin growths like skin tags. He also treats so called port wine stains (birth marks) and sun spots a feature of excessive sun exposure. All these treatments can be undertaken within the service at the Epsom Skin Centre in Epsom.
Conditions that can potentially be treated with lasers include:
- Facial thread veins
- Excess hair growth
- Sun freckles
- Unwanted tattoos
- Warty growths
- Certain moles
- Skin tags
