title: Wavelength-tunable and pulse-width variable Fourier domain mode-locking lasers.
abstract: In this study, wavelength-tunable and pulse-width variable Fourier domain mode-locking lasers were developed with a repetition rate of 60.9 kHz. A spectral laser tuning range of over 100 nm was achieved by tuning the offset voltage to a fiber Fabry-Perot tunable filter (FFP-TF). The pulse width variation was achieved with amplitude modulation of the driving voltage to the FFP-TF. The pulse width ranged from 6.2 μs to 55 ns. The linewidth of the laser changed, from 0.109 to 0.083 nm, according to the pulse width variation.
