  • Gain-switching — is a technique in optics by which a laser can be made to produce pulses of light of extremely short duration, of the order of picoseconds (10 12s).In a semiconductor laser, the optical pulses are generated by injecting a large number of carriers… …   Wikipedia

  • Optical overheating protection — With all solar thermal collector systems there is a potential risk that the solar collector may reach an equilibrium or stagnation temperature higher than the maximum safe operating temperature. Various measures are taken for optical overheating… …   Wikipedia

  • Optical heterodyne detection — is an important special case of heterodyne detection. In heterodyne detection, a signal of interest at some frequency is non linearly mixed with a reference local oscillator (LO) that is set at a close by frequency. The desired outcome is the… …   Wikipedia

  • Optical performance monitoring — (OPM) is used for managing high capacity dense wavelength division multiplexing (DWDM) optical transmission and switching systems in Next Generation Networks (NGN). OPM involves assessing the quality of data channel by measuring its optical… …   Wikipedia

  • Optical amplifier — An optical amplifier is a device that amplifies an optical signal directly, without the need to first convert it to an electrical signal. An optical amplifier may be thought of as a laser without an optical cavity, or one in which feedback from… …   Wikipedia

  • Optical parametric amplifier — An optical parametric amplifier, abbreviated OPA, is a laser light source that emits light of variable wavelengths by an optical parametric amplification process. Contents 1 Optical parametric generation (OPG) 2 Optical parametric amplification… …   Wikipedia

  • Optical parametric oscillator — Infrared optical parametric oscillator An optical parametric oscillator (OPO) is a parametric oscillator which oscillates at optical frequencies. It converts an input laser wave (called pump ) into two output waves of lower frequency (ωs,ωi) by… …   Wikipedia

  • Optical cavity — An optical cavity or optical resonator is an arrangement of mirrors that forms a standing wave cavity resonator for light waves. Optical cavities are a major component of lasers, surrounding the gain medium and providing feedback of the laser… …   Wikipedia
