A-Stack
Water-cooled laser diode stacks with real macro-channels that avoid the common issues with obstructions. The non-soldering technique used in the mounting of the laser bars, allows the use of electrodes with high thermal conductivity (near to 400 W/km). Furthermore both anode and cathode electrodes act as heat sinks and there is no thermal barrier between the laser bar and the electrodes. As a result, high cooling efficiency and large opertaion and storage temperature range are achieved.
A huge variety of laser bars is available in this package and the central wavelength can be tuned to your needs.

- Other wavelengths on request.
- Expected output power. Can varies based on current and temperature.
- Specification are subjected to chips availability.
- Voltage from the power supply must be higher, as due to high current there will be a voltage drop in the cables.
- Pitch dependent
