Using a same semiconductor laser scheme, the thermalimpedance of diamond thermal management is only 40% of AlN thermal management.
采用完全相同的半导体激光器结构,金刚石膜热沉的热阻仅为氮化铝热沉的4 0 %。

The effect of dielectric constant, dielectric loss factor, coefficient of thermal expansion (CTE)and characteristic impedance of substrate materials on properties of MMB are mainly discussed.
The alternating current impedance was used to examine the corrosion resistance. It is found that laser thermal shock improved the corrosion-resistant of the deeply drawing steel strip with Ni-coating.
