laser interferometer

laser interferometer

[′lā·zər ‚in·tər·fə′räm·əd·ər]
(optics)
An interferometer which uses a laser as a light source; because of the monochromaticity and high intrinsic brilliance of laser light, it can operate with path differences in the interfering beams of hundreds of meters, in contrast to a maximum of about 20 centimeters (8 inches) for classical interferometers.
