Laser Diode Bar

A laser diode ld injection laser diode ild or diode laser is a semiconductor device similar to a light emitting diode in which a diode pumped directly with electrical current can create lasing conditions at the diode s junction.

Laser diodes bars and multimode laser diode stacks are available in unmounted laser diode bars or mounted in conductively or actively cooled packages. Whether direct material processing or optical pumping of fiber lasers disc lasers or classical solid state lasers the laser bar is the key component for the initial conversion of electrical energy into light.

A diode pumped laser head usually the light is coupled into a single multimode fiber using either a simple fast axis collimator and no. Any wavelength akela laser corporation is a leading high power diode laser manufacturer specializing in custom laser diode products that offer a combination of any desired wavelengths ranging from 375nm to 12 microns and output power up to 1kw. Their portfolio of lasers tools and systems are used in a wide range of materials processing scientific applications. Opto semiconductor laser bars are the centerpiece of most of today s industrial laser systems.

3 laser diodes can directly convert electrical energy into light. Many diode bars are sold in fiber coupled form because this often makes it much easier to utilize their output and also makes it possible to mount the diode bars with their cooling arrangement in some distance from the place where the light is used e g. Driven by voltage the doped p n transition allows for recombination of an electron with a hole.
