Semiconductor lasers are lasers that use semiconductor materials as working materials. Semiconductor lasers are widely used in industrial manufacturing, scientific research, material processing, laser radar, detection lighting, medical health and other fields. With the continuous and in-depth application of new generation information technologies such as artificial intelligence (AI), the surge in demand for data throughput and computing power has opened up new market opportunities for the optical communication industry, especially in large-capacity and long-distance transmission. Optical communication, as a means of communication that uses light waves as information carriers, relies on semiconductor lasers to generate stable and high-intensity light beams to achieve high-speed data transmission. However, semiconductor lasers face many challenges in operation: non-radiative recombination losses and free carrier absorption in the active area of ​​their chips, coupled with the resistance of each layer of material, cause the laser to generate a lot of heat energy. If the heat cannot be dissipated in time, it will cause a series of performance problems such as wavelength red shift, threshold current increase, slope efficiency decrease, output power reduction, and even cause laser failure in extreme cases. Therefore, the optimization of heat dissipation packaging technology has become a core element to ensure the stable operation of semiconductor lasers. The heat dissipation of high-power semiconductor lasers mainly relies on a variety of technologies such as natural convection heat sink cooling, microchannel cooling, electric refrigeration, and spray cooling. Among them, the natural convection heat sink cooling method effectively reduces the temperature of the laser chip by using high thermal conductivity materials to make heat sinks and increasing the natural convection heat dissipation area. This method has become a widely used heat dissipation solution due to its easy processing and assembly characteristics. At present, the mainstream heat dissipation material for semiconductor lasers is aluminum nitride, and there are also some copper-tungsten alloys, diamonds, etc.
