Laser Diode
1. What makes the laser diode more efficient than the other lasers?
Laser diodes are more efficient because without the use of external pumping source, they convert electrical energy directly into coherent light.
2. What is the threshold current of a laser diode?
It is the minimum current which is required by the diode to achieve stimulated emission to produce the laser light. When the current is less than threshold value, laser diode behave as a LED.
3. Can laser diodes be modulated at high speeds?
Yes, many laser diodes can be modulated at high frequencies. It make them suitable for applications in telecommunications and data transmission.
Laser Diode
A laser diode is a small semiconductor gadget that produces strong and precise light emissions through a cycle called stimulated emission. These gadgets track down wide applications because of their proficiency and minimal size. When electric current flows through the p-n junction, the gain is generated through it. A laser diode is a semiconductor device that is identical to a light-emitting diode(LED) and converts electrical energy into light. In this article, we’ll learn about their development, working, types, and applications, and how these standardized gadgets work.
