to gain energy
1Gain (lasers) — Gain (or amplification) in laser physics is a process, where the medium transfers part of its energy to the emitted electromagnetic radiation, resulting in an increase in laser power. This is basic principle of all lasers.Quantitatively, the… …
2Energy policy — is the manner in which a given entity (often governmental) has decided to address issues of energy development including energy production, distribution and consumption. The attributes of energy policy may include legislation, international… …
3Energy balance — has the following meanings in several fields:* In physics, energy balance is a systematic presentation of energy flows and transformations in a system. Theoretical basis for an energy balance is the first law of thermodynamics according to which… …
4Energy transfer upconversion — or ETU is a physical principle (most commonly encountered in solid state laser physics) that involves the excitation of a laser active ion to a level above that which would be achieved by simple absorption of a pump photon, the required… …

6Energy — This article is about the scalar physical quantity. For other uses, see Energy (disambiguation). Energetic redirects here. For other uses, see Energetic (disambiguation) …
7Energy crisis — An energy crisis is any great bottleneck (or price rise) in the supply of energy resources to an economy. It usually refers to the shortage of oil and additionally to electricity or other natural resources. An energy crisis may be referred to as… …
8Energy Task Force — The Energy Task Force, officially the National Energy Policy Development Group (NEPDG), was a task force created by then U.S. President George W. Bush in 2001 during his second week in office. Vice President Dick Cheney was named chairman. This… …
9Gain-bandwidth product — The gain bandwidth product (GBW or GB) for an amplifier is the product of the open loop gain (constant for a given amplifier) and its 3 dB bandwidth. Relevance to design This quantity is commonly specified for operational amplifiers, and allows… …
10Gain graph — A gain graph is a graph whose edges are labelled invertibly, or orientably, by elements of a group G . This means that, if an edge e in one direction has label g (a group element), then in the other direction it has label g −1. The label function …
