• Second harmonic generation — (SHG; also called frequency doubling) is a nonlinear optical process, in which photons interacting with a nonlinear material are effectively combined to form new photons with twice the energy, and therefore twice the frequency and half the… …   Wikipedia

• Discrete spectrum — For a mathematically rigorous point of view of discrete spectrum , see decomposition of spectrum (functional analysis). In physics, an elementary (and accurate) explanation of a discrete spectrum is that it is an emission spectrum or absorption… …   Wikipedia

• Continuous spectrum — The spectrum of a linear operator is commonly divided into three parts: point spectrum, continuous spectrum, and residual spectrum. If H is a topological vector space and is a linear map, the spectrum of A is the set of complex numbers λ such… …   Wikipedia

• Frequency spectrum — Familiar concepts associated with a frequency are colors, musical notes, radio/TV channels, and even the regular rotation of the earth. A source of light can have many colors mixed together and in different amounts (intensities). A rainbow, or… …   Wikipedia
