China fiber laser research progress

In Nankai reported in 2002 4. 8ns pulse width self-Q-pulse output, and mixed Q-switched double-clad Fiber Optic Laser peak power is greater than 8kW in Yb3 +-doped double-clad fiber devices, pulse width less than2ns pulse output.

In 2003, Nankai University, reported that the pulse pump 100kW peak power Q-switched, and the 60nm tunable Q-switched.

Reported on November 20, 2003, Shanghai scientists to make new achievements in the field of laser output power up to 107W fiber laser successfully developed. Laser called "high-power ytterbium-doped double-clad fiber laser", its maintenance costs and power consumption is much lower compared with the currently available laser life is several times that of ordinary lasers. The researcher told reporters that the person in charge of the Task Force on the first floor Qihong laser printer has a wide range of applications, directly related to the life of the people, such as food production date, security signs, if the laser printing instead of ink print definition high, never fade, it is difficult to counterfeit, environmentally friendly, the new trend of international pop. Shanghai scientists have developed a fiber laser to the fiber laser output power increased to a new level, maximum output power of 107W, has been far ahead of the national counterparts.

In 2004, Nankai University, reported that the continuous pump 206kW peak power Q-switched pulse.

December 3, 2004, FiberHome reports, following the introduction of double-clad ytterbium-doped fiber laser output power up to 100W or more, through painstaking research new heights, the output power of this new class of fiber successfully increased to 440W, to achieve international advanced level.

This is an important step in the FiberHome step in the field of specialty optical fiber, also China a major breakthrough in optical fiber at high power lasers. Yb-doped double-cladVisible Fiber Laser is a newly developed a new type of high power laser devices, due to its good beam quality, high efficiency, easy to heat and easy to achieve high power characteristics, in recent years has developed rapidly and has become a high coherent light source candidates in the field of precision laser machining, laser radar systems, optical communications, and target designation. Double-clad layer of Yb-doped laser laser gain medium is a double-clad ytterbium-doped fiber double-clad layer of ytterbium-doped fiber performance directly determines the type of laser conversion efficiency and output power. The FiberHome only a double-clad layer of ytterbium-doped fiber research unit, after the successful launch of the output power up to 100W fully commercial double-clad ytterbium-doped fiber products, and increased research and development efforts, making the output power to achieve 440W, reached the international advanced level.

Fiber laser as a representative of the third generation of laser technology, with unparalleled technical superiority of the other lasers. However, we believe, in the short term, the fiber laser will be mainly focused on the high end applications with the popularity of the fiber laser, reduced costs and increased capacity will eventually may replace the out of the world's most high-power CO2 lasers and the vast majority of YAG laser.
