%X To the best of our knowledge, we have obtained the shortest fs tuning wavelength (1004 nm) ever obtained from a Yb-based solid-state laser system.  As the working horse, we have chosen Yb:YVO4 due to its blue-shifted gain spectrum. While using a single 10 W 952 nm diode for pumping and a semiconductor saturable absorber mirror (SESAM) for mode-locking, we have achieved 266 fs long pulses with up to 1.24 W of output power around 1021 nm. Using an intracavity birefringent filter, the central wavelength of the fs pulses could be tuned smoothly between 1004-1038 nm and 1009-1061 nm while employing the E//a and E//c axis of the material, respectively. Employing an additional hard aperture to increase the modulation depth, we have also achieved 100 fs level pulses in the 1012.5-1019 nm range, which shows the suitability of the system in seeding cryogenic Yb: YLF-based amplifiers.
