Widely tunable fiber-based optical parametric oscillator from 737 to 1014 nm

【摘要】 In this work,we demonstrate a widely tunable fiber-based optical parametric oscillator(FOPO) synchronously pumped by a high-power tunable picosecond Yb-fiber laser.The laser system features a compact and environmental-stable all-polarization-maintaining configuration.The wavelength tuning and cavity matching of the tunable Yb-doped mode-locked fiber laser(TYMFL) rely on an intracavity diffractive grating mounted on a motorized stage.By tuning the TYMFL from 1032 to1078 nm,the FOPO outputs from 737 to 1014 nm,which is the widest wavelength coverage in near-infrared FOPOs,to the best of our knowledge.All wavelengths can be tuned continuously and reversibly.The demonstrated FOPO is naturally synchronized with the TYMFL,enabling its application as a low-cost,highly flexible laser source in high-resolution coherent Raman scattering imaging.更多还原
