Production of high stable transform limited picosecond pulse trains using 1/2 rational harmonic mode-locking of a fiber ring laser

摘要

Wavelength tunable transform limited picosecond pulse trains with repetition rate from 4.78 MHz to 6.164 GHz have been obtained using 1/2 rational harmonic mode-locking of an erbium-doped fiber ring laser. The experiment shows that 1/2 rational harmonic mode-locking has a high stability on the variation of the bias voltage of the modulator and thus is very suitable for practical applications.
