AI Technical Summary
Technical Problem
In existing semiconductor lasers, the thermal stress of the bar module cannot be effectively released under high and low temperature cycling, resulting in a decrease in structural reliability and stability, and there is a risk of bar chip cracking.
Method used
Adjacent bar modules are connected by flexible and deformable metal foil. Stress is released by the deformation of the metal foil, and the modules are fixed by welding with gold-tin or tin alloy solder to ensure conductivity and structural stability.
Benefits of technology
It effectively releases thermal stress in the multi-bar series assembly, improves structural reliability and stability, extends service life, and enhances conductivity and laser beam quality.
