Single Emitter Free-Space Laser Diodes

Learn More About Single Emitter Free-Space Laser Diodes

Single-emitter free-space laser diodes are a key component in many optical systems due to their high-power output (especially multimode) and efficiency. The operation involves passing a current through a p-n junction in a semiconductor material. When the current passes through the junction, it excites the electrons in the material, causing them to emit photons – this is the process of stimulated emission, which generates the laser light.

One advantage of single-emitter free-space laser diodes is their efficiency. They can convert a large percentage of the input electrical power into light, making them a more energy-efficient choice compared to fiber-coupled lasers that experience a power drop due to fiber coupling inefficiencies for example.

Regarding free-space vs. fiber-coupled, the choice largely depends on the specific application. Free-space laser diodes offer the advantage of a more direct and efficient beam delivery, but they require precise alignment and are more susceptible to environmental factors. On the other hand, fiber-coupled laser diodes offer greater flexibility in beam delivery. They are less affected by environmental conditions, but they can be less efficient due to losses in the fiber.
