Selection of 1. laser: The laser is the core component of laser coherent beam combining, so it is necessary to select a suitable laser according to the actual demand.

2. Stability and reliability of beam: The stability and reliability of beam is one of the important indexes of laser coherent beam combining design, which needs to be fully tested and verified to ensure the stability and reliability of beam.

3. Optical path design: Optical path design is an important part of laser coherent beam combination design, and it is necessary to design an appropriate optical path according to actual needs. Optical path design includes optical path layout, selection and installation of optical elements, etc.
