Tunable All-fiber Laser with Fiber Grating

本文提出了一种利用光纤光栅作为调谐装置的可调谐全光纤激光器。实验结果表明：该调谐装置操作简便，性能稳定。激光器输出波长连续可调，输出波长复现性误差小于０．００８ ｎｍ ，输出功率大于１ｍ Ｗ，激光谱线线宽小于０．０１ ｎｍ ，波长调谐范围大于６．４ ｎｍ 。

Using fiber grating as the tuning element,we proposed a tunable all fiber laser.The experimental results confirmed its feasibility and stabilization.The wavelength of the laser can be tuned continuously with repetitive error less than 0.008 nm.The laser has output power more than 1 mW,line width less than 0.01 nm and wavelength tuning range more than 6.4 nm.
