Laser diodes are characterized by their inherent physical properties within five distinct categories, including: electrical, spatial, spectral, optical, and dynamic properties. For a detailed discussion of these physical properties of laser diodes, the reader is referred to Optical Emission in Semiconductor Materials and Laser Diode Light Characteristics. The combination of properties within these categories determines the performance and effectiveness of a given laser diode in terms of operational characteristics such as: Threshold current - the current at which the device begins to lase, Output power - the average output power generated by the device, Peak wavelength - the wavelength at which the greatest output power is observed.
