The simple laser diode structure described above is inefficient. Such devices require so much power that they can only achieve pulsed operation without damage. Although historically important and easy to explain, such devices are not practical. In these devices, a layer of low-bandgap material is sandwiched between two high-bandgap layers. One commonly used pair of materials is gallium arsenide (GaAs) with
