Free-Space Laser Diode Bars and Stacks

Learn More About Free-Space Laser Diode Bars and Stacks

In a laser diode bar, the active layer is formed by a series of emitting regions, known as emitters, separated by non-emitting areas. The configuration of these emitters, including their number, width, and spacing, varies depending on the manufacturer. The proportion of the active layer that is made up of emitting areas in relation to the total width of the bar is referred to as the filling factor (FF), which typically ranges from 30% to 90%.

Laser diode stacks consist of multiple laser diode bars arranged closely together, which allows for a higher total output power within a minimal area. These multimode diode stacks can be either actively cooled using Microchannel Cooling (MCC) or passively cooled, depending on the requirements for waste heat dissipation.

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.
