amplifying device
101Modelocking — Mode locking is a technique in optics by which a laser can be made to produce pulses of light of extremely short duration, on the order of picoseconds (10 12s) or femtoseconds (10 15s).The basis of the technique is to induce a fixed phase… …
102Audion tube — Audion redirects here. For other uses, see Audion (disambiguation). Triode Audion from 1908. (The 1906 Audion was a 2 element device with the signal applied to a wire wrapped around the glass envelope.) The Audion is an electronic amplifying… …
103Magnetic amplifier — The magnetic amplifier (colloquially known as a mag amp ) is an electromagnetic device for amplifying electrical signals. The magnetic amplifier was invented early in the 20th century, and was used as an alternative to vacuum tube amplifiers… …
