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