In laser diodes, population inversion is achieved through different pumping methods that excite electrons in the active region to higher energy states, enabling stimulated emission. The common methods are:

1. Electrical Pumping: This is the most widely used method in laser diodes, where an electrical current is passed through the diode. The electrons from the injector region are injected into the active layer, where they undergo recombination with holes, leading to photon emission. _________ ________ ____ _______ __________ _______ _________.
