Working Principle

The G061211000 laser diode utilizes the p-n junction of semiconductor material to generate a coherent beam of monochromatic light in the visible and near infrared range. The p-n junction produces an electric field across a semiconductor diode, which is used to generate light emission. The voltage-dependent electric field inside the diode locally polarizes the semiconductor material, causing electrons and holes to recombine and emit a photon when an electronic transition takes place.The electrons and holes are created by current passing through the diode’s materials and are represented by the n-type and p-type semiconductor regions on the pellet. The p-type material requires electrons to be injected from the metal contact while the n-type material requires holes to be injected from the metal contact. The electrons and holes recombine when an electronic transition occurs and emit a photon, which is then amplified by the laser diode to produce a coherent light beam. The G061211000 laser diode is designed to operate in a temperature range of -25°C to +55°C, and is capable of producing a maximum power output of 200mW over a wide range of wavelengths. The device has a wide operating voltage range of 8~13V, allowing it to be used in a variety of applications. The diode also offers a wide variety of package options, including a 5.6mm can package, which can be mounted onto a variety of laser systems. Additionally, the G061211000 offers excellent beam profile control and a long lifetime, making it an ideal choice for many laser applications.

Conclusion

The G061211000 laser diode from Coherent is an ideal choice for many micro-machining, optical communications, and observation instrumentation applications.
