Definition, characteristics and technology of ultrafast laser. Ultrafast lasers include picosecond and femtosecond lasers, which are characterized by very short pulse time and high peak power. In order to achieve the above characteristics, three core technologies are adopted: Q-switching technology, mode-locking technology and CPA technology. The difficulty of ultrafast laser technology increases gradually with the shortening of pulse time.
The application and market space of ultrafast laser. Ultra-fast lasers are mainly used in precision processing because of their short pulse time and high peak power. The applications of ultra-fast lasers include OLED, semiconductor, medical and other precision industries. By 2020, the market size of ultrafast pulsed lasers is expected to exceed US$1.5 billion. Its growth rate is twice that of the laser market as a whole, with an expected growth rate of 20%-30%. And with the increase of the power of ultrafast lasers, it will make the market more and more widely used.
Foreign enterprises invest in the embrace of large companies, and domestic small lotus emerges. The development of foreign ultra-fast laser companies presents two patterns: one is that they have their own core technology, which was acquired by the leading enterprises in the laser industry and put into the embrace of large enterprises; the other is that they develop independently. At present, it has been acquired by large enterprises into the mainstream. The main reason is that Ultra-Fast Laser Enterprises are generally start-ups with small scale, but the leading enterprises in the laser industry are concerned about the rapid growth and market potential of Ultra-Fast Laser, and have entered the Ultra-Fast Laser Industry through mergers and acquisitions. At present, domestic ultra-fast lasers are in the initial stage of development, but also produced excellent enterprises such as Huari Laser, Belin Laser, Anyang Laser and so on. From the product layout, most enterprises have the capacity to produce picosecond lasers, and gradually improve the power of picosecond lasers. At present, the highest power is up to 50W. Femtosecond lasers are mainly produced by foreign manufacturers, especially ultraviolet femtosecond lasers, which are controlled and monopolized by foreign manufacturers. At present, some domestic enterprises have broken through the research and manufacture of ultraviolet femtosecond lasers.
