دیود لیزر 1.6W دارای طول موج 450nm

A laser diode, (LD), an 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 can directly convert electrical energy into light. Driven by voltage, the doped p-n-transition allows for the recombination of an electron with a hole. Due to the drop of the electron from a higher energy level to a lower one, radiation, in the form of an emitted photon is generated. This is a spontaneous emission. Stimulated emission can be produced when the process is continued and further generate light with the same phase, coherence, and wavelength.

These laser diodes are designed for maximum performance and reliability. Operating the laser diode above the maximum rating even for very short periods of time can damage the laser diode or reduce its lifetime. The laser diode must be operated with a suitable power supply with minimized electrical noise.

The laser diode is very sensitive to electrostatic discharge (ESD). Proper precautions must be taken.

In order to maintain the lifetime of the laser diode, proper heat management is essential. Due to the design of the laser diode heat is dissipated only through the base plate of the diode‘s body. A proper heat-conducting interconnection between the diodes base plate and the heat sink must be maintained.

However, diode lasers not only prove themselves with their high output powers but are also popular because of their high energy efficiency. With a socket output efficiency of about 50 percent, they achieve the best efficiency of all current laser types. And although a beam of hundreds of single emitters must be combined at the diode laser, the technology reaches even with respect to focusing very good values.

Depending on the mode of operation, these devices emit highly concentrated visible light which can be hazardous to the human eye.

Products that incorporate these devices have to follow the safety precautions found in IEC 60825-1 "Safety of laser products."
