Semiconductor laser
The document discusses the properties and operating principles of semiconductor lasers. It defines the threshold conditions required for lasing, including the threshold population inversion and threshold current density equations. It also examines key laser characteristics such as output power, differential efficiency, and power conversion efficiency as functions of operating current above the threshold current density. The maximum efficiencies are achieved at high injection levels well above threshold.
