Diode lasers gets superior advantages of small size, light weight, high efficiency etc. It has got high attention from the very beginning of its creation, which is widely used in a large variety work fields of industry, military, medical, communication etc. However, due to their limited quantum well waveguide structure, the output power laser beam quality is much weaker than solid-state lasers, CO2 lasers, thus in a certain period, the development of diode laser system is seriously limited.
