In these days laser diodes have many uses in the fields like telecommunications, military applications and medicine. This is somewhat similar to light emitting diode as it has semiconductor as its active medium. The technology of laser diode has changed quickly from the early 60s. We can define laser diode as a semiconductor device that emits waves when power runs through them. These have external and internal feedback cavities that are used to trigger laser action. The available colors are blue, blue-violet and green to red. The act of using of the laser diode depends upon the position on the spectrum light as well as its wavelength.

Uses:-

Laser diodes are the most common type of laser. However, they are very small in size. They are used in barcode readers, optical mice, laser pointers, fiber optics and medical equipment. The laser diodes used in laser printers, laser pointers, CD planners and bar code scanner are of similar types. However the large ones are used in many defense applications. The pulsed laser range-finders used in military tanks produces a powerful light that can destroy rockets, land mines and ...
... other ordinances. It has also many benefits in the medical industry. The cosmetic applications such as intense pulsed light for age spot, hair removal, wrinkle removal has become possible for this.

Though these are not risky like solid or gas state lasers, still they should be used with care. The laser diodes are put up inside the unit. They are not meant to be seen. Laser pointers are highly visible and have a higher output. These may cause headaches, visual distraction if not properly used. These are small and useful. They are increasingly powerful these days. Just be aware when using this and avoid the enticement to look at it or change it anyway.

The difference between red and green laser is the wavelength of the beam. They have various wavelengths. In case of green laser, the process of creating laser beam is very difficult in comparison to red ones.A green laser module can be built in many ways. These are quite complicated in comparison to red lasers. Instead of this, now they are made as well as sold with much less price.

There are many manufacturers of custom designed laser diode modules. These are mainly used in military, medical, biotechnology and other high-end fields. There are manufacturers that make the greatest efforts to conserve energy and resources while manufacturing the products.
