What are Laser Diode Stacks?

Laser Diode Stacks: In a laser diode bar, the individual emitting areas (emitters) lie side by side, separated by the non-emitting areas. These sets of emitting/non-emitting regions form the so-called active layer.

Learn More About Laser Diode Stacks

The number, the width, and the spacing of the emitters is manufacturer dependent. The relative value of the emitting areas in the active layer with respect to the bar width is the filling factor (FF). Typical filling factors are 30 – 90%. The center-to-center distance between two adjacent emitters is the emitter pitch. Z is the propagation axis of the laser radiation. The propagation axis Y is the fast axis (FA) and the X axis is the slow axis (SA), referring to the rate of divergence. Therefore, these axes comprise the beam angle (divergence) in the two planes, XZ and YZ.

Our Laser Diode Stack Products

Our laser diode stacks are multiple laser diode bars packaged in close proximity. Therefore, increasing the total output power in the smallest area possible.  Multimode diode stacks can be actively cooled with Microchannel Cooling (MCC) or passively cooled depending on the waste heat requirements.  We offer a wide range of wavelengths and output powers up to 1440W CW and up to 2400W QCW.

We offer options in near infrared (NIR) wavelengths ranging from 808nm-980nm. These stacks have free-space output and collimation options for fast axis, slow axis, or both axes.

JOLD-Stacks Series

The JOLD–Stacks Series offers a highly modular approach for power scaling well into the kW-range through vertical stacking of individual sub-mounts within multi-laser-bar packages. Our optimized beam quality (BPP) is achieved through our unique approach of reducing the pitch of neighboring stacks without compromising cooling capacity. Our proven hard-solder technology and strictly monitored production processes ensure tried & tested reliability under even the harshest environmental conditions. The series also features microchannel-cooled packages for CW-operation, actively cooled with deionized (DI) water.
