We report wavelength-tunable operation of a Tm-doped silica fiber laser by using a force-induced long-period fiber grating (LPFG) formed in a fiber ring resonator. The laser output wavelength is tuned by moving the transmission passband that is generated between adjacent resonance wavelengths due to the force-induced LPFG. By changing the grating period around 900 μm, we control the laser output wavelength between 1845 and 1930 nm.
我们报道了一种通过使用在光纤环形谐振器中形成的力致长周期光纤光栅(LPFG)实现的掺铥石英光纤激光器的波长可调谐操作。通过移动由力致LPFG在相邻谐振波长之间产生的传输通带来调谐激光输出波长。通过在900μm左右改变光栅周期,我们将激光输出波长控制在1845至1930nm之间。
