Laser cutting machine manufacturers learned: Recently, IPG Photonics released the 2014 second quarter performance report. Data show that the company achieved revenue of US $ 192.2 million in the second quarter and net profit of US $ 48.28 million, of which high-power fiber lasers and materials processing applications contributed significantly . It is reported that in the first quarter of 2014, IPG achieved operating income of US $ 170.6 million, an increase of 20% year-on-year; net profit was US $ 40.53 million, an increase of 15% year-on-year. Therefore, IPG achieved total revenue of US $ 362.8 million and net profit of US $ 88.81 million in the first half of 2014. "The demand for high-power fiber lasers has grown significantly," said the company's CEO, Dr. Valentin Gapontsev. "Laser cutting and welding, 3D printing, glass cutting and laser cleaning applications drive laser material processing applications to maintain an annual growth rate of 18%. . And high-power fiber lasers maintain a 2OFweek laser net growth rate of 2%. Geographically, Europe and Asia have made outstanding contributions to performance growth. "
IPG was incorporated in Delaware, United States in 1998. The company is a major developer and manufacturer of a variety of high-performance fiber lasers. Its main R & D and production bases are located in the United States, Germany, and Russia. It is the only vertically integrated company. Fiber laser manufacturer. Products are widely used in materials processing, medical and communications. Whether it's a Gillette shaver or Volkswagen, the production of these daily necessities is inseparable from the IPG fiber laser. At present, about 30% of lasers are fiber lasers, and the fiber laser industry continues to seize the share of traditional lasers in manufacturing, especially cutting and welding applications. Compared with traditional lasers, fiber lasers improve versatility, reduce energy consumption, and reduce operating and maintenance costs. IPG's operating income in 2013 was US $ 648 million, an increase of 15.2% compared to US $ 562 million in 2012; net profit was US $ 156 million, an increase of 7.43% compared to US $ 145 million in 2012. Among them, the substantial increase in sales of IPG high-power fiber lasers is mainly due to the growing demand for laser cutting and welding in automotive, heavy industry and manufacturing. At the same time, in order to meet the growing demand for fiber lasers, IPG announced earlier this year that following the acquisition of Veeco Instruments' molecular beam epitaxy (MBE) system in the United States, it plans to use Veeco's molecular beam epitaxy system to target its laser diodes. For mass production.
Technical principle of fiber laser Fiber laser refers to the laser using rare earth element-doped glass fiber as the gain medium. Fiber laser can be developed based on fiber amplifier: high power density is easily formed in the fiber under the action of pump light, resulting in The laser energy level of the laser working substance is "particle number inversion". When a positive feedback loop (forming a resonant cavity) is appropriately added, a laser oscillation output can be formed. As early as 1961, E. Snitzer of the American Optical Corporation and other pioneering work in the field of fiber lasers, but due to the limitations of related conditions, its experimental progress is relatively slow. In the 1980s, SB Poole from the University of Southhampton in the United Kingdom made low-loss erbium-doped fibers using MCVD, which brought new prospects for fiber lasers. The basic structure of fiber laser is shown in Figure 1. Fiber lasers can use fiber gratings as cavity mirrors to achieve all-fiber structures. The pump light is coupled into the gain fiber from the left cavity mirror. The pump light is repeatedly reflected through the doped core in the cladding. The fiber has a sufficient length and the concentration of doped ions. Can fully absorb the pump light. The fiber laser is a waveguide-type resonant cavity device. The transmission of light waves is borne by the optical fiber. This structure is actually a Fabry-Perot cavity structure. A fiber laser is actually a wavelength converter. At the pump wavelength, the photons are absorbed by the medium, the number of particles is reversed, and finally stimulated emission and output laser are generated in the doped fiber medium. Figure 1 Schematic diagram of the basic structure of a fiber laser. According to different gain media, fiber lasers can be divided into two categories: doped fiber lasers and stimulated fiber lasers. The gain medium of the doped laser is mainly a rare earth fiber, and the laser generation mechanism is stimulated radiation. The emission mechanism of the stimulated scattering fiber laser is a non-linear effect, mainly stimulated Raman scattering and stimulated Brillouin scattering.
According to the structure of the laser cavity, it can be divided into linear cavity, annular cavity, etc., as shown in Figure 2. Fiber gratings are used instead of cavity mirrors, and linear cavities are further divided into distributed feedback (DFB, Distributed-Feedback) and distributed Bragg reflector (DBR). The linear cavity fiber laser has a simple structure and can achieve high power and single longitudinal mode output. The structure of a two-ring cavity fiber laser is more complex, and usually has multiple longitudinal mode outputs. Schematic diagram of fiber laser structure (a) Linear cavity (b) Ring cavity can be further divided into continuous laser and pulse laser according to the time domain characteristics of laser output. Pulsed fiber lasers are usually implemented with Q-switched and mode-locked technologies. Mode-locked technologies are divided into active and passive mode-locking.
The key technologies of fiber lasers can be divided into: special fiber technology, cladding pump coupling technology, fiber grating technology, semiconductor pump laser technology, and fiber laser technology. Strong growth in the field of fiber laser application At present, the largest market for fiber lasers is in the kilowatt class and above. Among them, two-dimensional sheet metal cutting is the main application of kilowatt fiber lasers. The domestic high-power cutting machine market has a demand of nearly two thousand units per year. . High-power laser welding and other applications have greater market potential. In 2013, the situation of the global industrial laser processing industry was more complicated: the U.S. market has grown by virtue of its outstanding performance in exports; Europe has maintained its balance of payments by virtue of German export growth; the growth of ASEAN countries in the Asian market has offset China's economic slowdown And zero growth in Japan. In 2013, the industrial laser material processing market size increased by approximately 3.6%, reaching US $ 2.393 billion. The market demand in this field drives the continuous growth of the global laser processing market, and its main business covers marking, micromachining and material processing.
In 2013, the industrial laser marking and OFweek laser screen engraving market size reached USD 342 million, with an annual growth rate of 13%. Among them, fiber lasers occupy a major position, accounting for about 66% of such equipment, and the sales revenue of lasers used in marking and engraving fields is 227 million US dollars. In 2013, materials processing accounted for the largest proportion of the total laser size, reaching $ 1.474 billion. It is mainly reflected in high-power lasers with higher yields for processing metals with a thickness of more than 10mm. In terms of lasers, CO2 lasers accounted for 47% of material processing and accounted for 36% of overall laser revenue; fiber lasers grew 24% in 2013. It is estimated that high-power fiber lasers have penetrated the sheet metal cutting market (up to 35%); direct semiconductor lasers increased by 26%. Among them, the sales revenue of fiber lasers (≥1 kW) in the field of application and material processing in 2013 was US $ 432 million. Nowadays, the share of fiber lasers in various business fields is constantly increasing, which promotes the development of the global laser market. Fiber lasers are favored by system integrators for their advantages of high efficiency and low maintenance and operating costs. Low-power pulsed and continuous-wave fiber lasers have revolutionized the global marking and engraving industry, gradually replacing lamp-pumped and diode-pumped solid-state lasers. In terms of high-power fiber lasers, with the continuous maturity of technology, the power has become larger and larger, and the market share of CO2 lasers has been eroded in terms of material processing, and the annual growth rate has reached 20%.
