Laser light has many special properties but those most relevant to medical applications are the monochromaticity, the ease of precise control and the ability to focus the full out-put of a high power laser on to a very small area. The latter property makes it practical to deliver laser light of appropriate wavelengths to internal parts of the body via single flexible fibres and to limit the effect to the desired target organ with greater accuracy than is possible with other techniques. Many lasers are currently under investigation for their biological effects, ranging from wavelengths in the far infra-red to the far ultra-violet, both continuous wave and pulsed. The properties of the most important ones are outlined in tables 1 and 2.
