Aluminium gallium indium phosphide

is a semiconductor material that provides a platform for the development of multi-junction photovoltaics and optoelectronic devices.

[1] AlGaInP is used in heterostructures for high-brightness red, orange, green, and yellow light-emitting diodes.

[citation needed] A diode laser consists of a semiconductor material in which a p-n junction forms the active medium and optical feedback is typically provided by reflections at the device facets.

AlGaInP diode lasers emit visible and near-infrared light with wavelengths of 0.63-0.76 μm.

[4] Illumination by an AlGaInP laser was associated in one study with slower healing of skin wounds in laboratory rats.
