| laser-doppler flowmetry | A method of non-invasive, continuous measurement of microcirculation. The technique is based on the values of the doppler effect of low-power laser light scattered randomly by static structures and moving tissue particulates. (12 Dec 1998) |

| lasering | The use of a laser beam to cut, divide, or dissolve a substance, or to treat an anatomical structure. (05 Mar 2000) |
| lasers | Light amplification by stimulated emission of radiation. This phenomenon is brought about using devices that transform light of varying frequencies into a single intense, nearly nondivergent beam of monochromatic radiation in the visible region. Lasers operate in the visible, infrared, or ultraviolet regions of the spectrum. They are capable of producing immense heat and power when focused at close range and are used in surgical procedures, in diagnosis, and in physiologic studies. (12 Dec 1998) |
| laserwort | <botany> Any plant of the umbelliferous genus Laserpitium, of several species (as L. Glabrum, and L. Siler), the root of which yields a resinous substance of a bitter taste. The genus is mostly European. Origin: L.laser the juice of the laserwort. Source: Websters Dictionary (01 Mar 1998) |
