摘要
We demonstrate an all-fiber and continuously wavelength-swept fiber optical parametric oscillator (FOPO) based on dispersion tuning technology around 1 mu m. The alignment-free FOPO is pumped by a pulse train light, driven by a frequency-swept electric pulse source with a repetition rate ranging from 107.24MHz to 107.31 MHz. Thus, the FOPO demonstrates a wavelength-swept output with a sweeping range of 100 nm centered at 1065.10 nm. The sweeping rate can be improved up to 100 kHz, while the cumulative speed exceeds 1000 000 nm s(-1). Since the electric scanning is used in an all-fiber setup instead of the traditional mechanical scanning method, it demonstrates better stability under prolonged operation, which is promising to be applied in biomedical imaging, such as optical coherence tomography (OCT) systems and other applications.
