What is a Laser Diode?Laser Diode DefinitionA laser diode is defined as a diode that can generate laser light when electrically pumped with current. It consists of a p-n junction with an additional intrinsic layer in between, forming a p-i-n structure. The intrinsic layer is the active region where the light is generated by the recombination of electrons and holes.The p-type and n-type regions are heavily doped with impurities to create excess carriers, while the intrinsic layer is undoped or li
