beam width — The full angular interval in the horizontal plane between the points at which the power radiated from the antenna has fallen to half its maximum value. In practice, the effective beam width may be less than this value and may be altered by use of … Aviation dictionary
Beam diameter — The beam diameter or beam width of an electromagnetic beam is the diameter along any specified line that is perpendicular to the beam axis and intersects it. Since beams typically do not have sharp edges, the diameter can be obtained in many… … Wikipedia
Beam parameter product — In laser science, the beam parameter product (BPP) is the product of a laser beam s divergence angle (half angle) and the radius of the beam at its narrowest point (the beam waist).cite web|url=http://www.rp photonics.com/beam parameter… … Wikipedia
Power dividers and directional couplers — A 10 dB 1.7–2.2 GHz directional coupler. From left to right: input, coupled, isolated (terminated with a load), and transmitted port … Wikipedia
Laser beam profiler — A laser beam profiler captures, displays, and records the spatial intensity profile of a laser beam at a particular plane transverse to the beam propagation path. Since there are many types of lasers ultraviolet, visible, infrared, continuous… … Wikipedia
