| 摘 要： | 利用相位长周期光纤光栅作为光谱滤波器,熔接于全正色散掺镱光纤激光系统中,从而实现了具有波长可调谐的连续激光输出和被动锁模激光脉冲输出,可调谐激光波长范围分别为11.4 nm和10.5 nm.通过调节偏振片改变激光腔内的偏振状态,输出锁模脉冲实现脉冲宽度的可调谐,其调谐范围为3.6~1.2 ns.在530 mW的最大泵浦功率下,得到了重复频率为2.5 MHz、最大单脉冲能量为38.9 nJ的锁模脉冲输出和最大输出功率为124 mW的连续激光输出.

| Abstract: | Both tunable continuous-wave(CW) and passively mode-locked pulses of all-normal dispersion (ANDi) Yb-doped fiber laser (YDFL) with phase-shifted long period fiber grating (PS-LPFG) as a all-fiber format spectrum fused in the laser cavity was reported and demonstrated, in which the output wavelengths can be tuned over a spectral range of 11.4 nm for the CW mode and 10.5 nm for the mode-locking mode, respectively. |

| Keywords: | tunable Yb- doped fiber laser nonlinear polarization rotation long period fiber grating all normal dispersion |
