● It is very easy to work with laser diodes as these are very small. As these diodes have small size and highly efficient pumping, it makes them useful in applications such as optical data transmission and data storage, spectroscopy, medicine, and pumping solid-state lasers.
● They have much simplistic construction than other types of lasers.
● The light generated by these diodes is of high efficiency.
● The operational power used by the laser diodes is less than other light-emitting devices.
The active layer (light emission layer) sandwiched between the p- and n-type clad layers (double heterostructure) is formed on an n-type substrate, and voltage is applied across the p-n junction from the electrodes. Both edges of the active layer has mirror-like surface.When forward voltage is applied, electrons conbine with holes at the p-n junction, and emitt the light. This light is not a laser yet; it is confined within the active layer because the refractive index of the clad layers are lower than that of the active layer. In addition, both ends of the active layer act as a reflecting mirror where the light reciprocates in the active layer. Then, the light is amplified by the stimulated emission process and laser oscillation is generated.
The Basic Principle Of Digital Laser Diode
The active zone of digital laser diode consists of a pn junction layer, which serves as a light-generating medium. Here, charge carriers are injected by a current source. These recombine in the semiconductor layer and emit photons. The band gap of the semiconductor material determines the emission wavelength. By choosing the respective semiconductor material, a spectrum of ultraviolet (UV) to infrared (IR) radiation can be realized.
Like other lasers, the digital laser diode requires an optical cavity in which photons are amplified by stimulated emission. This is formed by two partially transparent mirrors arranged in parallel. As soon as the amplification in the cavity is greater than the losses, the diode starts to lase. Some highly developed variants, such as DFB (distributed feedback) digital laser diodes or VCSELs (vertical cavity surface-emitting lasers), use special resonator concepts to improve spectral purity and beam quality.
Consumer electronics
Digital laser diodes are used laser printers, CDs and DVD players, and fiber optic communication.
Medical applications
Digital laser diodes are used for removing unwanted tissues and tumors.
Industrial applications
Digital laser diodes are used as a source of a high-intensity laser beam in many industrial applications and are particularly used for cutting, drilling, welding, etc.
Scientific instrumentation
Digital laser diodes are also popularly used in measuring instruments such as spectrometer, range finders, contact-less measurement can be done with the help of laser diodes.
