| Popis: | We report on the generation of femtosecond blue pulses from a two-branch mode-locked erbium-doped fiber source. This is achieved by sum-frequency mixing in β-barium borate between the frequency doubled laser radiation at 770 nm and a tunable near-infrared component generated inside a highly nonlinear fiber. Small angle tuning of the nonlinear crystal leads to a continuously variable output wavelength in the visible band between 460 nm and 500 nm. Average power levels exceeding 1.5 mW were collected throughout the entire tuning range of our device, which delivered sub-300-fs pulses at a repetition rate of 98 MHz. These values indicate that the input near-infrared radiation is up-converted with a photon efficiency of 20%. |
