Active mode-locking via pump modulation in a Tm-doped fiber laser
APL Photonics, 2016 We propose and experimentally realize a new class of actively mode-locking technique using pump modulation for rare-earth doped fiber lasers. A Tm-doped fiber laser at 2 μm is mode-locked using the proposed active mode-locking via pump modulation ...

Effect of noise on the power spectrum of passively mode-locked lasers [PDF]
, 1997 We analyze the effects of noise on the power spectrum of pulse trains generated by a continuously operating passively mode-locked laser. The shape of the different harmonics of the power spectrum is calculated in the presence of correlated timing ...
