HFD3180-103

Laser Diodes, Modules

The HFD3180-103 is a laser diode module that features a red laser light with a wavelength of 635 nm, output power of up to 2.3 W, and a high beam divergence of 1.2 mrad. It is a semiconductor laser diode containing a pair of very high-speed transistors. Unlike conventional semiconductor diodes, the HFD3180-103 has a permanent polarized crystal structure, as well as two dopants at both ends of the crystal. Because of this unique structure, it is able to generate a high-intensity light output.

The HFD3180-103 is used mainly in laser printers and barcode scanners, but it can also be used in other applications such as medical equipment, fiber optic communication systems and range finders. The HFD3180-103 can also be used in laser engraving and cutting, where the intense light beam focuses energy onto a small area, causing it to heat up sharply and vaporizing the material in its vicinity. It is also used in optical data storage, where the laser writing and erasing of optical compact discs is based on the laser diode\'s light emission.

Working Principle

The basic process of a laser diode module is generally the same regardless of the type of diode used, and involves two main steps: pumping and emission. First, pumping takes place in the semiconductor material which is usually made up of either gallium arsenide (GaAs) or indium gallium arsenide (InGaAs).Here, electrons are injected into the laser diode\'s "active" region, where by the injection of the correct amount of energy, the population inversion is achieved. This population inversion is required for the laser light to be emitted.

Secondly, laser emission takes place when electrons from the conduction band of the active region combine with electrons from the valence band. In doing so, they emit photons of light in the form of coherent quantum of energy. This emission is repeated from each of the available energy levels in the laser diode\'s crystal, resulting in a steady stream of light with a wavelength determined by the materials used during the pumping process.

Applications

The HFD3180-103 is used primarily in laser printing, where it is used to print barcodes, graphics and other information on paper or other media. It is also used in medical equipment, such as lasers for surgery and eye surgeons. It can also be used in range finders for military and optical data storage. Additionally, the HFD3180-103 laser diode can be used in laser engraving and cutting, as well as lighting and display applications.

Because of its wide range of uses, the HFD3180-103 is an incredibly versatile component. It is capable of a variety of tasks and can be adapted to different objects and environments. Its high beam divergence and power output make it especially suitable for applications that require a precise, powerful laser.

The HFD3180-103 is a reliable, cost-effective device that can be used in a range of applications. Its high power output, excellent beam divergence and long-term stability makes it an excellent choice for many different industries. As a result, it is a popular choice for laser modules, power electronics and biological applications.
