The aluminium gallium indium phosphide laser is a type of visible-light diode laser. Visible diode lasers emit wavelengths of red and green in the visible spectrum of electromagnetic radiation. The diode lasers consist of a semiconductor material in which the p-n junction forms the active medium.
The AlGaInP laser emits wavelengths of 0.63-0.9 µm. Each of these wavelengths is used for different applications. Electric current is used as a pumping source for these lasers.
The physical properties and applications of this laser are discussed in the sections below.
