Abstract

In this article, we achieve the output observation in time and frequency domain of a rational harmonic mode‐locked fiber laser (RHMLFL). The pulse amplitude of pulse train is equalized by operating at nonlinear modulation transfer function region of active modulator in RHMLFL. Without adding any other additional predistortion components, amplitude equalized short pulses up to the fourth order rational harmonic mode‐locking are successfully demonstrated for 7.5, 10, and 15 GHz. One can extend such a method for various mode‐locked lasers even with much higher repetition rates. © 2008 Wiley Periodicals, Inc.

Soliton self-frequency shift in a highly nonlinear photonic-crystal fiber is shown to enable an efficient wavelength conversion of 100-fs 70-MHz output of a solid-state ytterbium laser, allowing the generation of sub-100-fs laser pulses with a central wavelength tunable from 1060 to 1400 nm. In the
