According to the latest report from IMARC Group, the global fiber laser market will grow at a CAGR of around 8% in 2021-2026. Factors such as rapid industrialization and increasing adoption of advanced technologies to automate various manufacturing processes are among the key factors driving the growth of the fiber laser technology market. In addition to this, fiber lasers are gaining popularity in the healthcare industry due to the growing prevalence of chronic diseases. They are used in settings such as dentistry, photodynamic therapy, and biomedical sensing in the mid-infrared spectrum. Furthermore, with the growing demand for electric vehicles (EVs), the application of fiber lasers in internal combustion engines (ICEs) is expected to increase.
At present, China has become the world's largest manufacturing country, and the domestic market has an increasingly strong demand for laser technology products. Since 2010, thanks to the continuous expansion of the laser processing application market, China's laser industry has gradually entered a period of rapid development. In 2018, the scale of China's laser equipment market reached 60.5 billion yuan, a year-on-year increase of 22.22%, and the compound growth rate from 2011 to 2018 reached 26.45%. China Business Industry Research Institute predicts that China's laser equipment market will reach 98.8 billion yuan in 2021.
The three principal applications of broadband light sources are as follows. Let’s take a quick look at each one to get a better understanding of them.
According to the order of Russian Prime Minister Mikhail Mishustin, the Russian government will allocate 140 billion rubles over 10 years for the construction of the world's first new synchrotron laser accelerator SILA. The project requires the construction of three synchrotron radiation centers in Russia.
A femtosecond laser is an "ultrashort pulse light" generating device that emits light only for an ultrashort time of about one-gigasecond. Fei is the abbreviation of Femto, the prefix of the International System of Units, and 1 femtosecond = 1×10^-15 seconds. The so-called pulsed light emits light only for an instant. The light-emitting time of the flash of a camera is about 1 microsecond, so the ultra-short pulse light of femtosecond only emits light for about one billionth of its time. As we all know, the speed of light is 300,000 kilometers per second (7 and a half circles around the earth in 1 second) at an unparalleled speed, but in 1 femtosecond, even light only advances by 0.3 microns.
The team of Professor Rao Yunjiang of the Key Laboratory of Optical Fiber Sensing and Communications of the Ministry of Education, University of Electronic Science and Technology of China, based on the main oscillation power amplification technology, realized for the first time a multimode fiber random with an output power of >100 W and a speckle contrast lower than the human eye speckle perception threshold. Lasers, with the comprehensive advantages of low noise, high spectral density and high efficiency, are expected to be used as a new generation of high-power and low-coherence light sources for speckle-free imaging in scenes such as full field of view and high loss.
