We confirmed the thermal resistance between bonded surfaces of the distributed face-cooled (DFC) gain media, which were made of Nd:YAG and sapphire. It indicates that the surface activated bonding technology enables us to enhance the 10 W/mK of the YAG thermal conductivity over 27 W/mK effectively.
