Semiconductor lasers are a class of lasers that have matured earlier and progressed faster, due to its wide wavelength range, simple production, low cost, easy mass production, and due to the small size, light weight and long life, therefore, the variety of rapid development, a wide range of applications, there are more than 300 kinds of semiconductor. The most important applications for lasers are as pump sources for fibre lasers and solid-state lasers. Currently, semiconductor lasers with output powers ranging from 2kw to 6kw are widely used in the automotive industry. Semiconductor lasers cover the entire field of optoelectronics and have become the core technology of optoelectronics science today. Semiconductor lasers have gained a wide range of applications in telecommunications and communications, optical storage and display, and medical applications, creating a broad market.
The most common types of semiconductor lasers on the market are: Blue lasers are lasers that emit electromagnetic radiation at wavelengths between 360 and 480 nanometres, which can be seen by the human eye as blue or violet. A red laser is a laser with a wavelength of 630-680nm and a power of 5mw or less. An infrared laser is a laser with an infrared laser, which is an electromagnetic radiation laser with a longer wavelength than visible light.

Semiconductor Laser Market Analysis Forecast
The semiconductor laser industry has become the cornerstone of the entire laser industry, and the laser industry has become an integral part of the life of human society. According to Laser Focus World data, the global semiconductor laser market size continued to grow in 2017-2018 and fell to US$14.7 billion in 2019 due to the escalating trade war between the US and China, as well as weakness in some European markets and a significant drop in the price of fibre laser products. Despite the impact of the new crown epidemic, economic recession in some regions and social and political unrest in 2020, the global laser market has maintained a relatively stable growth, reaching $15.8 billion in 2020 and is expected to reach $27.3 billion in 2026, at a compound annual growth rate (CAGR) of 7.7%.
Among the world leaders in the semiconductor laser market are Sony, Nichia, QSI, Sharp, ROHM, Ushio, Osram, TOPTICA Photonics, Huaguang Optoelectronics, Panasonic, Hamamatsu, Newport Corp. EgismosTechnology, Arima Laser, Finisar, Mitsubishi Electric and Coherent (Ondax), among others. These top companies currently account for more than 41% of the total market share.
Asia Pacific became the world\'s largest and fastest growing region, accounting for 37.5% of total sales of semiconductor lasers in 2013. The most important reason for this was the further expansion of the communications market in Australia, South Korea and India, as well as in Asia Pacific countries such as China. North America and Europe continued to grow steadily due to improving economic conditions.
China\'s Development Needs in the Semiconductor Laser Industry
China\'s primary need in the development of the semiconductor laser industry is to protect national strategic security. Semiconductor lasers are the core components of optical communication, laser sensing, laser processing, laser pumping, and can also be directly applied to laser radar, laser ranging, laser weapons, missile guidance, optoelectronic countermeasures and other fields.
Building a complete closed-loop industrial chain, forming positive feedback, promoting the accelerated maturation of front-end core chips through market applications, and using mature chip technology to drive new achievements and new applications to the ground is the best path that should be chosen for the development of the relevant industries in China.
China\'s semiconductor laser industry has long been in the catch-up phase, and it is an urgent need for the industry to lead in certain areas. From a practical point of view, for new applications, the development of new devices, to occupy the "first mover advantage", is an effective way to achieve beyond.
Based on the above considerations, the new system laser industry, which is still a certain distance away from the real maturity of the market, is undoubtedly an important breakthrough to solve this contradiction. Firstly, the gap between China and foreign countries in terms of research and development of new regime lasers is relatively small. Supported by the policy bias in recent years, China has made long-term development in the field of cross-disciplinary integration as well as emerging semiconductor lasers. Especially in the field of micro and nano optics and micro and nano lasers, our researchers have participated in or hosted many of the world\'s top research results through international cooperation. If these results can be transferred industrially, it will certainly lay a good foundation for the development of China\'s new system semiconductor laser industry. Secondly, the new system laser involves the field of basic physics. China has attached importance to the construction of basic disciplines in recent years, which has provided a talent base and development momentum for the development of new system lasers. Finally, in the field of new system laser industry, foreign development is in the same initial stage as ours, through the national funding and policy support, China\'s new system laser development will have the ability to take a place in the development of the world\'s new system laser industry.
The accumulation of technology and industrial development cannot be achieved overnight, and the difficulties encountered should be faced squarely at the same time as seeing hope. The development of China\'s semiconductor laser industry is still in a relatively backward state, whether in terms of technical theory, talent reserves or process flow and production equipment are far behind the advanced foreign enterprises. The scale of enterprises is still dominated by small and medium-sized private enterprises, and the products produced mainly face low- and mid-range applications, unable to achieve an essential industrial change. The export of technology is still based on a single technology or a single patent, unable to form a complete industrial chain development, moreover, unable to establish a perfect "industry-university-research" combination system. Manufacturing equipment is still mainly imported equipment, strongly dependent on foreign technology output, unable to achieve real independent intellectual property rights. Therefore, policy support in the relevant direction is imminent.
