Laser diodes form a subset of the larger classification of semiconductor p – n junction diodes. Forward electrical bias across the laser diode causes the two species of charge carrier – holes and electrons – to be injected from opposite sides of the PIN junction into the depletion region.

The wavelength of a laser is measured in meters (nanometers, micrometers, millimeters, etc. When monochromatic light passes through a diffraction grating, it produces a characteristic diffraction pattern due to the interference of light waves. In this document we'll describe a method for measuring the line width of single longitudinal mode lasers. It is a key procedure of measuring the diode laser wavelength in the wavelength modulation spectroscopy (WMS) technique since it determines the selection of specific modulation amplitude and frequency and thus the overall accuracy of the WMS technique.

The active region of the laser diode is in the intrinsic (I) region, and the carriers (electrons and holes) are pumped into that region from the N and P regions respectively. Laser diodes are semiconductor devices that emit coherent light when electric current passes through them. Amplification of light by stimulated photon emission produces a monochromatic, directional, coherent, and high-intensity beam. As a light source with excellent directivity and rectilinear propagation that enables easy control of energy, laser diodes are used. These gadgets track down wide applications because of their proficiency and minimal size.
