[0003] A high-power laser diode array is actually a regular arrangement ...

AI Technical Summary

Problems solved by technology

Because the light emitted by the laser diode has a large divergence angle, and the luminous intensity per unit area sometimes cannot meet the requirements of high-power solid-state lasers, it needs to be collimated and converged when side pumping

Coupling methods such as lens groups, cylindrical lens groups, and direct pumping are mainly used in China, which have disadvantages such as complex structure, low efficiency, and uneven pumping.
