We report a wavelength-tunable harmonically mode-locking dissipative soliton fiber laser based on a high-speed intensity modulator with a simple all-polarization-maintaining (all-PM) cavity. The center wavelength can be precisely tuned from 1029.35 to 1079.25 nm by tuning only the frequency of the pulse pattern generator (PPG), and the linear tuning accuracy of the wavelength can reach 0.0093 nm/kHz. The degree of polarization can reach 98.969%. The FWHM of the pulse is measured to be 30.1 ps, and the intracavity pulse energy after the gain fiber can reach 5.41 nJ. All orders of the harmonic mode-locking repetition rate are tuned from ∼33.346 to ∼366.806 MHz through adjustment of the data length and frequency of PPG.
我们报道了一种基于高速强度调制器和简单全保偏（all-PM）腔的波长可调谐谐波锁模耗散孤子光纤激光器。通过仅调节脉冲模式发生器（PPG）的频率，中心波长可在1029.35至1079.25 nm范围内精确调谐，波长的线性调谐精度可达0.0093 nm/kHz。偏振度可达98.969%。测得脉冲的半高全宽为30.1 ps，增益光纤后的腔内脉冲能量可达5.41 nJ。通过调整PPG的数据长度和频率，谐波锁模重复率的所有阶次可在约33.346至约366.806 MHz范围内调谐。
