A laser is also known as laser diodes (LD), and light-emitting diode (LED) is an optoelectronic device, both devices generated light. But the way they emit light have different characteristics.
The laser emits converging light while the output of the LED is highly divergent. Eyes protection should be used when dealing with these optoelectronic devices, especially in the case of Laser as it generates high energy beam.
Why are laser diodes preferred over LED? What are the key attributes that make them different from each other?
