Abstract

To raise the capability of heat-sinking of slab laser amplifier, which is the type of conduction cooling, we need to weld crystal and heat sink with micro channel together. Slab laser module with high power and good beam quality is required to reduce welding void ratio and lower thermal distortion. In this paper, we offer a welding process of slab laser module with large size. With an accurate travel control system, it can adjust welding gap between slab and heat sink. We get low welding void rate of 2.3% in large area of 3600 mm2 with the system by measuring in ultrasonic scanning microscope.
