amplified spontaneous emission; ASE; superluminescence
Technical physics term for light produced by spontaneous emission that is subsequently amplified by stimulated emission in a gain medium. Used in laser physics and photonics.
Amplified spontaneous emission is a phenomenon observed in the pre-oscillation stage of lasers.
In this fiber amplifier, amplified spontaneous emission becomes a noise source.
Stimulated emission; the process by which an incoming photon triggers an excited atom to emit a second photon. ASE involves both spontaneous and stimulated emission.
Laser; a device that produces coherent light through stimulated emission. ASE is often an unwanted precursor or noise in laser systems.
Compound of 自然 (natural/spontaneous), 放射 (emission/radiation), 増幅 (amplification), and 光 (light). A direct translation of the English term 'amplified spontaneous emission'.
