  Diode Laser Module Market – Summary A diode laser is a device capable of generating a lasing action by applying a potential difference across a modified p-n junction. This modified p-n junction is heavily doped and contained within a cavity thus providing the gain medium for the laser. A feedback circuit is also implemented in order to control the amount of current sent to the diode laser. The diode lasers can be made from many different types of semiconducting materials including several elements found in groups III and V from the periodic table. A few examples of these materials include GaAlAs, AlGaInP, InGaAsP. Some of the most common uses for diode lasers are in everyday devices such as CD ROMs, CD players, laser disc and mini disc players, and also laser printers and laser fax machines. Other uses might not seem so easily thought of, such as in medicine, interferometry, and bar code scanners, but are still used by many people every day. These diode lasers are often used in t...
