frequency-controlled laser
1Frequency Scanning Interferometry — (FSI) is an absolute distance measurement technique, for measuring the distance between a pair of points, along a line of sight. The power of the FSI technique lies in its ability to make many such distance measurements, simultaneously. For each… …
2Laser cutting — process on a sheet of steel. CAD (top) and stainless steel laser cut part (bottom) Laser cutting is a technology that uses a laser to cut materials, an …
3Laser trimming — describes the manufacturing process of using a LASER to adjust the operating parameters of an electronic circuit.The usual approach is to use a laser to burn away small portions of resistors, raising their value (resistance). The burning… …
4Laser diode — Top: a packaged laser diode shown with a penny for scale. Bottom: the laser diode chip is removed from the above package and placed on the eye of a needle for scale …
5Laser — For other uses, see Laser (disambiguation). United States Air Force laser experiment …
6Frequency comb — A frequency comb is the graphic representation of the spectrum of a mode locked laser. An octave spanning comb can be used for mapping radio frequencies into the optical frequency range or it can be used to steer a piezoelectric mirror within a… …
7Laser pointer — A laser pointer is a portable, pen sized laser designed to be held in the hand, and most commonly used to project a point of light to highlight items of interest during a presentation. Most laser pointers have low enough power that the projected… …
8Laser safety — A typical laser warning symbol. Laser safety is safe design, use and implementation of lasers to minimize the risk of laser accidents, especially those involving eye injuries. Since even relatively small amounts of laser light can lead to… …
9laser — /lay zeuhr/, n. Physics. a device that produces a nearly parallel, nearly monochromatic, and coherent beam of light by exciting atoms to a higher energy level and causing them to radiate their energy in phase. Also called optical maser. [1955 60; …
10Laser — A powerful beam of light that can produce intense heat when focused at close range. Lasers are used in medicine in microsurgery, cauterization, for diagnostic purposes, etc. For example, lasers are employed in microsurgery to cut tissue and… …
