In this paper we will introduce the structure and the principle of the high power diode stack. This is mainly due their low performance. So all developed countries have attached great importance to high- power diode laser system and its applications. In addition, High power diode lasers in the military field also have important applications. hardening, key hole welding, cutting and metal welding. But there are some applications, which require much higher power and brightness, e.g. At this power level, it can have many important applications, such as surgery, welding of polymers, soldering, coatings and surface treatment of metals. Respectively, diode laser could make it possible to establish the practical application because of rectangular beam patterns which are suitable to make fine bead with less power.
As diode laser is simple in structure, small size, longer life expectancy with the advantages of low prices, it is widely used in the industry processing, such as heat treating, welding, hardening, cladding and so on. High- power diode lasers based on GaAs semiconductor bars are well established as reliable and highly efficient laser sources.

Next, data are presented on a 9.5 kW peak power array at 900 nm having a narrow emission bandwidth suitable for pumping Yb:S-FAP laser materials. First, performance and reliability of an optimized large transverse mode diode structure at 808 and 941 nm are presented. High power laser diodes at various wavelengths are described. High- power laser diodes at various wavelengths A comparison of the advantages direct diode laser versus traditional industrial lasers such as CO2 and Nd:YAG and non- laser technologies such a RF induction, and MIG welders for each of these production applications is presented. Each of these applications uniquely tests the direct diode laser systems capabilities and confirms their reliability in production environments. These applications are laser hardening/surface modification, laser wire feed welding and laser paint stripping. We discuss several novel applications in which the HPDDL have been implemented and proven reliable and cost-effective in production environments. There has been many novel applications described for high power direct diode laser systems but few have been implemented in extreme production environments due to diode and diode system reliability.
