High-power Laser Diode Assembly
Where would we be without laser diodes
and the myriad devices that are made with them?
The laser diode is one of the most common devices used throughout photonics. The micro-assembly process calls for the placement and bonding (align-&-attach) of single emitters, or multiple laser diodes (stacked or complete bars), the placement, active alignment and bonding of necessary micro-optical elements, subsequent device testing, and ultimately packaging and quality control.
ficonTEC’s machine systems are capable of all the steps necessary for assembling laser diodes, even high-power devices. Multiple in-line systems can be configured to address entire process segments.

FAQs
What level of alignment accuracy and process stability can be achieved?
Our align & attach systems are designed for sub-micron accuracy using active alignment with multi-degree-of-freedom control and closed-loop feedback systems.
This ensures highly stable and repeatable processes, even for demanding high-power laser diode applications where coupling efficiency and thermal stability are critical.
Which applications and industries are HPLD assembly solutions used for?
HPLD assembly solutions are used across a wide range of industries, including telecommunications, industrial laser systems, medical technology, LiDAR, and aerospace.
They are particularly relevant for applications that require high optical output power, precise beam characteristics, and long-term reliability under demanding conditions.
How flexible are your systems in terms of integration into existing production lines?
Our systems are modular and can be configured as standalone workstations or fully integrated into existing production environments.
We support inline automation concepts and offer customization options to match your specific process flow, footprint, and throughput requirements.
This ensures seamless integration without the need to redesign your entire production setup.
