Optically Pumped VECSELs: A Primer

Any semiconductor has a valence band and a conduction band, separated by a bandgap where electrons are forbidden.

In an electrically pumped semiconductor laser, a junction between dissimilar semiconductors is formed in which electrons and holes combine when a current passes through the device. An electron starts in the conduction band and a hole in the valence band, and a photon is created when they combine...
