Vertical CW diode laser stacks

Vertical CW diode laser stacks

Our vertical stacks can be used to increase the optical output power of your diode laser. To do so, we stack up to 16 mounted laser bars to form a diode laser stack or an assembly. each of these laesr bars individually supplies up to 100 watts in cw mode. Because of the small gaps between the laser bars, you obtain maximum brilliance from the stacks, enabling you to work highly effective. You can choose between laser diode stacks with a Fast-Axis (FA) or without collimation.vertical cw diode laser stack
