Laser Diodes, Modules are semiconductor devices designed to emit high-intensity beam-focused radiation in the form of infrared, visible, or ultraviolet wavelengths. The ranges include the electromagnetic spectrum and coherent light waves of similar wavelength, phase, and direction.
Laser Diodes
Laser diodes (also called injection lasers or diode lasers) are semiconductors that generate coherent radiation in the visible or infrared (IR) spectrum by passing a current through them.
Working Principles of Laser Diodes
Laser diodes work the same as LEDs; however, they produce a precise beam of light at their junction. They are ideal for applications that acquire accurate data readings. They produce a robust output determined by their optical output power.
Laser Modules
Laser modules are packaged power modules comprised of laser diodes along with embedded elements. For instance, they feature cables that connect to the power and are often made of aluminium. Another type of laser module called a continuous wave laser with a continuous output beam remains constantly ON until switched OFF.
They are ideal for laser printing, barcode reading, and fiber optic applications. These are available in various wavelengths (laser’s output colour) measured in nanometers, which indicate varied colours.
Available Laser Diodes, Laser Modules
We stock items for almost all applications, with different power ranges ranging from 1 milliwatt to several watts. We provide varied peak optical power, input voltage, and case and current sizes. Furthermore, laser diodes are in stock with several packages available in various colours, including green, blue, and red.
