land
In a CD-ROM disc, the reflective area between nonreflective pits representing a binary-language "off'' as opposed to the "on'' signals of the land-to-pit and pit-to-land transitions.
laser cavity
A laser cavity, also known as an optical cavity or resonator, is a fundamental component of a laser system. It is a confined region or space where light undergoes multiple reflections, leading to the...
laser damage threshold
The laser damage threshold refers to the maximum level of laser intensity that a material can withstand without experiencing damage. It is a critical parameter in laser applications and is...
laser diode

diode laser
A diode laser is a type of laser that uses a semiconductor diode as the active medium to generate coherent light. Semiconductor diodes are electronic devices that conduct electricity primarily in one...
laser line filter
A narrow linewidth optically transmissive or reflective component intended for use with a highly monochromatic or single mode source.
laser oscillator
Contains the light or beam path within a laser device. The oscillator uses reflective optical components that are oriented to obtain multiple confined reflections.
laser
A laser, which stands for "light amplification by stimulated emission of radiation," is a device that produces coherent and focused beams of light through the process of optical amplification based...
lens blank
A lens blank is a piece of optical material in a raw, unfinished state, typically in the form of a disk or block, from which lenses are eventually fabricated. Lens blanks are made from various...
Linnik interference microscope
A Michelson-type interference microscope used to produce interference patterns of reflective specimens through the interference between light reflected by the specimen and that reflected by a...
liquid crystal on silicon
Liquid crystal on silicon (LCoS) is a display technology that combines liquid crystal materials with silicon-based semiconductor technology to create high-resolution, high-quality images. LCoS...
