inhomogeneously broadened laser
1Optical 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… …
2Homogeneous broadening — If an optical emitter (e.g. an atom) shows homogeneous broadening, its linewidth is its natural linewidth (see spectral linewidth). In contrast, an inhomogeneously broadened emitter has a broader linewidth than the natural. Broadening in laser… …
