我们通过实验证明了在大法向色散范围内工作的全光纤被动锁模激光器的脉冲能量增强。通过增加激光腔长度及其净腔色散，所提出的激光器通过非线性偏振旋转锁模，产生脉冲能量高达 9.4nJ 的高啁啾耗散孤子。基本重复率为2.3MHz，脉冲持续时间为35ps。如此低的重复率和宽脉冲宽度使这种锁模全光纤激光器成为直接播种光纤放大器的合适振荡器，可用作高功率应用的紧凑型光源。
We experimentally demonstrate pulse energy enhancement in an all-fiber passively mode-locked laser operating in the large normal dispersion regime. By increasing the laser cavity length as well as its net cavity dispersion, the proposed laser, which is mode-locked by nonlinear polarization rotation, generates highly chirped dissipative solitons with pulse energies up to 9.4nJ. The fundamental repetition rate is 2.3MHz, and the pulse duration is 35ps. Such low repetition rate as well as wide pulse width makes this mode-locked all-fiber laser a suitable oscillator to directly seed a fiber amplifier, which can be used as compact sources for high-power applications.
