Is laser light emitted from diodes
A laser diode (semiconductor laser) is an electronic component that generates laser light by converting electric current into light using a semiconductor p-n junction. As a light source with excellent directivity and rectilinear propagation that enables easy control of energy, laser diodes are used. A laser diode is a small semiconductor chip that converts electrical current directly into a focused beam of light. It uses p-n junction to emit coherent light in which all the waves are at the same frequency and phase.
