Laser pointers are used widely today, and the laser you see coming out from the laser pointer consists of a high power laser diode. A laser diode consists of a laser which makes use of a semiconductor as a medium that is pretty much like a light emitting diode. A high power laser diode is used in a lot of different applications today, with laser pointers, pens, and laser lights being the most popular applications.
Title: Complete analysis of a high power laser diode
Before we begin to analyze a high power laser diode, the first thing you need to understand is how the laser diode operates. A laser diode is formed when a thin layer is doped on a crystal wafer. The doping of the crystal is done in a manner which allows the creation of ann-type portion as well as a p-type region, with the latter being on top of the other. This is the reason why it is said that a high power laser diode can only function on the basis of an n-p junction. You can easily spot the usage of a high power laser diode in everyday applications, such as laser pens, pointers and laser guns. The maximum output that can be generated by a 650 nm laser diode is around 200 mW. The wave that it outputs is a continuous one, which means that you would find no interruption when the wave is being generated.
Two AAA batters are required to work the high power laser diode, and the powerful 650 nm laser diode can be used for pointing at objects at very large distances, such as the moon or stars. A powerful visible light is emitted whenever an electric current is passed on through the crystal wafer, which is what generates the light. The power outputted by the 650 nm laser diode is around 200 mW, which when converted to the distance that can be travelled by the laser light comes out to be 6,000 ft.
The surprising part about the high power laser diode is that it does not consume that much energy as most people would suspect, and with a pair of AAA batteries, you can easily get a clear laser emission from the laser diode. With a simple flick of a switch, you can produce a clear emission of a powerful laser beam. These laser beams are used highly in telecommunications as well, as they blend in very well with fiber optics communication wires.
Laser pointers are used widely today, and the laser you see coming out from the laser pointer consists of a high power laser diode. A laser diode consists of a laser which makes use of a semiconductor as a medium that is pretty much like a light emitting diode. A high power laser diode is used in a lot of different applications today, with laser pointers, pens, and laser lights being the most popular applications. So, overall I am happy to remark it as 10/10.
