What is LiDAR? Short for Light Detection and Ranging, LiDAR is a remote sensing method that irradiates objects using near-infrared, visible, or UV light then detects the reflected light with an optical sensor to measure the distance. Also called Laser Imaging Detection and Ranging, it is ...
A semiconductor laser is a laser that uses a semiconductor as the gain medium. The gain medium is the active element of the device that amplifies light. It is typically made from materials like carbon atoms or silicon atoms. When pumped with electrons, these materials can produce photons, the...
The most common function of a diode is to let the electric current run in one direction (known as the diode’s forward direction), even as it blocks the flow in the other/ opposite direction (aka the reverse). In a manner of speaking, the diode is an electronic version of the check ...
What is a laser diode?What is a laser diode? The LASER in Laser Diode is an acronym for 'Light Amplification by Stimulated Emission of Radiation'. Semiconductor Laser Features and Applications Semiconductor Laser is used for a variety of applications by taking advantage of characteristics. LD ...
A laser diode is a device used in electronics that converts light into electricity. A laser diode is a type of p-n junction semiconductor laser with two mirrors facing each other and two electrodes. When current flows through the device, light is emitted by the bandgap of the active region...
A diode is a specialized electronic component, specifically a two-terminal semiconductor device, with two electrodes called the anode and the cathode. It has several uses: as a one-way switch that enables current to flow easily in one direction while restricting its flow in the other direction,...
Semiconductor Physics Behind Diode Operation The operation of a diode is deeply rooted in semiconductor physics. At the atomic level, the p-type material is doped with atoms that have one less valence electron than required, creating 'holes'. Conversely, the n-type material is doped with atoms...
Find out exactly what a laser is, how it works and the most common applications in our Spectral School article, What is a Laser?
A laser diode is a type of semiconductor diode that can generate laser light. The three conditions for generating laser light are: achievingpopulation inversion, meeting threshold conditions, and resonance conditions. Because laser diodes have a very high sensitivity to static electricity,we shouldpay...
The behavior of a diode is similar to the behavior of a check valve. One of the most important characteristics of a diode is the non-linear current voltage. If higher voltage is connected to the anode, then current flows from anode to cathode, and the process is known as forward bias. ...
